There has much been written about the G-Spot (named after its discoverer, Grafenburg). It is an area within the woman’s vagina that, when stimulated, can bring intense pleasure. Now due to the advances in non-invasive anatomical investigation with MRIs, CAT scanners, and other highly sensitive investigative instruments, the human form is revealing more of its secrets. Here we examine two newly discovered pleasure areas within the general area of the female genital zone. The U-Spot. The U-spot is a small area of highly sensitive erectile tissue located just above and on both sides of the urethral opening. Some American clinical researchers have recently discovered this aera, and proved that if it was stimulated by caress, with the tongue, the head of the penis, or even a lubricated finger, it brought an unexpected and highly intense erotic response. This is not the urithiral opening, but just above and to ether side of it. There is no U-spot underneath the urithra towards the vagina. Care should be taken when attempting to stimulate it, and ask for feedback from your partner. The Anterior Fornix Erogenous Zone (also known as the A-Spot or T-Spot ,or just AFE) Recently a Malaysian physician reported the existence of a highly sensitive erotic area just above the cervix, at the innermost point of the vagina. The cervix is a part of the uterus that extends slightly into the vagina. As it so extends, it leaves a depressed circular area, technically called the anterior fornix. Tests have shown that pressure on this area causes the vagina to lubricate very quickly. In fact, direct stimulation of the AFE zone can cause immediate and profound contractions only found in orgasm. Some anatomists say the AFE zone is really a evolutionary degenerated prostate, homologous to a man’s prostate gland that would be located in just about the same place. The AFE – Zone and Erotic Pleasure Technically, the AFE Zone is a vortex of the nerves that carry information from your whole genital to the spinal cord and brain. These nerves, when stimulated, send arousal signals to the part of your nervous system which enhances engorgement of appropriate areas, ans is responsible then for sexual arousal. This is also true for women that normally are not sexually responsive. Obviously the most easy way to locate the AFE zone is to slide the fingers halfway up the posterior vaginal wall you will find a larger area than the G-spot, which is slightly rougher than the normal vaginal wall. Recently specially shaped vibrators (long, then and with the neck bent in an oblique way) have come onto the marketplace which are meant for self-stimulation of the AFE zone. Size Matters? This is long-standing debate on the benefits or deficiencies of a large and long penis. In the case of the AFE zone, no matter the size of a man’s penis, he must be experienced to find, and then stimulate the AFE zone. For the man with a shorter penis, there are some advantagous positions to shorten the woman’s uterous, and thus still find a way to stimulate the AFE zone as well. The use of the advanced missionary, where the woman will have her legs drawn to her breast, with the man’s arms both holding her legs apart, and suspending himself, will create, even if he is short and small of penile stature, complete penetration and stimulation of the AFE zone. Due to small depression at its location, and roughness of the area, it also provides some intense pleasure for the man as well. penis enlargement pills pro solution home penis enlarement free exercise tip for penis elargement herbal natural penis enlargment vimax best penis enlargement surgery buy place vigrx natural penis enhancement exercise pnis girth enlargement

Don't feel well? Take a pill. A few pounds to lose? Take a pill. No energy? Take a pill. Depressed? Take a pill. Today's society is a pill society. Many studies have been done to show that if people are given a placebo (sugar pill) and told that it will increase their sexual performance; the majority will say that they noticed an increase in their sexual performance. It has proven that enhancing the libido, at least the most important part of it, comes from the mind. So now we wonder, how does food affect a person's sexual and emotional health? Soy can be used to suppress hot flashes that occur hot flashes, promote a healthy prostate, and help in vaginal lubrication. It adheres to estrogen receptors which maintain the lubrication that a vagina needs. This is a problem that also occurs during menopause. Chili peppers can improve your circulation and stimulate nerve endings. Ginger can do the same thing. Because this improves, so will your sexual pleasure. Since good blood flow is important for a good erection food that is good for your heart will also be good for your penis. If your heart is not operating properly there is a very good chance that your penis will not be responding as well as you would like it to either. Since saturated fat will clog the arteries, which in turn will restrict the blood flow, it stands to reason that it also restricts the blood flow that reaches your genital region as well. Yes, your body does require fat to create hormones, but it needs the right kind of fats. Good fat comes from olive oils, sea food, and nuts. These good fats will help in the production of hormones that are essential for sexual peak performance. Foods that are said to have aphrodisiac qualities are asparagus, bananas, eel, oysters, figs, and ginseng. Rhino horn is said to increase the sexual appetite. The taste, texture, or perhaps appearance of these foods are thought to increase the sex drive. There are some that believe if you eat foods that appear penis like it will make your penis strong and like the food that you ingest. The same applies to the oyster or the fig, which either smell or look like the woman's vulva when aroused. When a person eats these foods they are in the hopes that the vulva will then become plump, slippery, and tasty as well. Sweet or spicy foods are thought to put people in a relaxed mood and to appear ready to take on more pleasure. Now the question remains, do these food myths work? No, not the way that they are said to work. Foods cannot change the way that your sexual organs look. Food can be a great way to spice up your sex life though, so why not? Drinking alcohol will relax you emotionally and physically make you look flushed. For a short amount of time it will make you look flushed. Caffeine and sugar offer a quick boost of energy. These are short term effects but in reality what you should do is eat a healthy diet of fish and fresh vegetables to be at your best physically and sexually at all times. You can make food part of your sexual experience by cooking a mean with your lover and feeding it to each other. Have a picnic in the middle of the floor, place the foods all around you and let your imagination take over. 'The Karma Sutra' suggests boiling a ram's or goat's testicle in sweetened milk with sparrow's eggs and rice and honey for an aphrodisiac. penile enlargment fact free penis enlargement video vimax male penis enlargement plastic surgery penile enlargement best pnis enlargement free penis enlargment exercise penis enlargment pic before and after natural penis elargement and lengthening penis enlargment pic before and after

As we human beings have changed and evolved over our thousands of years of recorded history so have our attitudes and expressions of all things sexual. The only thing that hasn’t changed much is society’s desire to exercise a certain amount of control over an individual’s sexual behavior. Whether it be through church or state, educational institutions or popular media of the time, there have been rules and regulations, views and taboos about what we should do sexually, how we should do it, who we should do it with and even how we should think about doing it. BODY PARTS A particular area of interest, naturally, has been the body and specifically those parts that are obviously connected with sex. We’ve alternately hidden and displayed, worshipped and derided male and female genitalia. In most non-Christian cultures there were gods and goddesses of power and fertility with exaggerated genitals. Some cultures liked penis gods so much they had several, for instance the ancient Greeks honored Priapus, Dionysus and Hermes. The Egyptians exalted Osiris, Bacchus was the Roman version, and Shiva reigned in India. Penis and, less commonly, vulva worship, were practiced and this was reflected in objects connected with daily living. Vases in classical Greece were decorated with phalluses. In the ruins of Pompeii penis symbols were found just about everywhere, on bowls, lamps and figurines. Pitchers with enormous penis spouts were a unique specialty of the Mochica culture of Peru. The exteriors of medieval Irish churches were adorned with sculptures of Shelah-na-Gig, a vulva icon. In Egypt enormous symbols of penis power – the obelisk – were erected all over the landscape. Smaller penis symbols in the form of amulets and bracelets were worn as magical protection against evil in ancient Rome. In fact, the English word ‘fascinate’ is derived from ‘fascinum’ the Latin word for these magic penis images. Words describing body parts vary from culture to culture and often reflect the attitudes we have about them. In India and China the penis and vagina were approached with respect and awe. Terms like Jade Flute, Arrow of Love, Ambassador, Warrior for the penis and Valley of Joy, Ripe Peach, Lotus Blossom, Enchanted Garden for vagina were used. In the English language however, words are much more likely to be discourteous: dick, tool, meat, dong and pussy, crack, slit. Cock and prick are two of the longest-standing terms for penis in English. Prick was actually a pet name up until the seventeenth century when times became much more prudish and prick gradually became ostracized. Now it’s used not as a term of endearment but of scorn. Cock, another penis word, comes from the name for the male barnyard fowl but in the late seventeenth century uptight early Americans were so offended by this that they began calling the bird rooster. Other common objects also had their names changed to make them more seemly: haycock turned into haystack, weathercock into weathervane, and apricock into apricot. Yiddish slang words for penis include schlong, putz and schmuck. Believe it or not in 1962 comedian Lenny Bruce was arrested because he used the terms schmuck and putz in his act! When it comes to penises, many cultures have considered bigger to be better. But in classical Greece delicate and small penises were the best. Big sex organs were thought to be ‘coarse and ugly’. During this time young athletes worked out in the nude. As protection for his private parts a man pulled his foreskin over the head of his penis, tied it with a ribbon and then fastened the ribbon ends to the base of the shaft. This precursor to the modern jock strap was known as a dog knot. Other means of protecting and, in most cases, emphasizing the penis include codpieces, sheaths and even paper sculptures. Codpieces, which are brightly colored and gaily ornamented pouches for penis and testicles, were worn by Europeans over tight breeches and under short jackets during the fourteenth through sixteenth centuries. Protective and decorative penis sheaths were common among primitive societies. Made out of everything from leather and vegetable fibers to bamboo, gourds and shells these sheaths were the mainstay of a man’s wardrobe. From the ninth to the twelfth centuries Japanese men packaged their penises inside an animal shaped paper sculpture. This practice was designed to increase sexual pleasure: the penis would take on the qualities of the animal it was packed inside and the lovers would then act out fantasies stirred up by the animal package. LOOK BUT DON’T TOUCH Although we’ve been fascinated by and have focused on our genitals since time began, in many cultures there has paradoxically been a policy of look but don’t touch, at least not your own. Self-pleasuring, or masturbation, has been vilified for a number of reasons. For instance the Taoists in China condemned male masturbation to the point of ejaculation as wasteful because too much ‘yin’ or masculine energy would be lost with the expelled semen. The Christian church raised masturbation to a level of damnable sin. Penitential books published by the church during the eighth century, which outlined proscribed sexual practices and their accompanying penalties, emphasized masturbation over any other sexual offence. From the eighteenth century onward doctors and scientists joined in the battle against self-pleasuring. Leader of the pack was Swiss physician Simon Andre Tissot who in 1758 preached that masturbation would stimulate an increase in blood pressure in the head thereby damaging the nervous system and causing insanity. Other doctors quickly joined the battle, blaming masturbation for such ills as: acne, backache, blindness, constipation, epilepsy, gout, infertility, nymphomania and vomiting. These were not the opinions of a few quacks but commonly held beliefs throughout western society. From the 1850s until the 1930s thirty-three patents were issued in the U.S. to inventors of anti-masturbation devices. These painful and humiliating gadgets included such items as: spermatorrhea bandages, which bound the penis so tightly to the body that erection was not possible; a spike-lined ring which drove sharp metal points into a penis that was becoming erect; sexual armour, clothing with metal crotches which had holes through which urine could escape but which had to be unlocked at the back for defecation; the “Stephenson Spermatic Truss”, a pouch which tied the penis back and down between the legs; and a harness which would ring an alarm and give an electric shock when a penis attempted to enlarge! It wasn’t until Alfred Kinsey, in his ground-breaking research about sex that began in the 1930s, proclaimed that over 90 percent of men admitted to masturbating at least once that attitudes began to relax. SEXUAL RELATIONS Most likely because from the Neolithic period (10,000 – 4,000 BC) up until the late 17th century it was believed that men alone were responsible for producing children through the magic of their semen, women ranked second in just about everything including sex. Women were viewed as childbearers and as objects for male sexual satisfaction. Often it was not the same woman who filled both roles. In almost all cultures from ancient Egyptian, Babylonian, Greek, Indian, Asian and on, women belonged to their fathers when they were young and then to their husbands when they reached marriageable age. Their behavior, particularly sexual, was most often highly restricted. The ancient Hebrews stoned women to death for adultery. Early Romans could kill their wandering women as well. Later they were simply obliged to divorce them as were husbands in classical Greece. Europeans kept their women from straying through the use of chastity belts which first appeared there during the 12th century and became quite popular during the 1400s and 1500s. Many chastity belts were secured by padlocks, some had rigid metal bands which could be tightened or loosened depending on the mood of the husband. Ironically, it was female members of the so-called ‘oldest profession’, prostitution, who in many societies had a certain amount of freedom and even influence. In Sumerian times (2,000 B.C.) prostitutes were respectable members of the temple. Through sex with a sacred prostitute Sumerian worshippers paid homage to their gods. Part of the prostitutes’ value was that their earnings contributed substantially to the temples’ income. Temple prostitutes were common in Greece and Rome, India, and even early Christian Europe. In Avignon, France there was a church brothel where the women divided their time between servicing clients and carrying out religious duties. Top-level courtesans enjoyed a more liberated status than other women during many eras, ancient Greece, Confucian China, 15th century Rome, Louis’ France, and a few were able to become very successful women in a man’s world. They often received better education, had more social freedom and wielded influence in politics. BIRTH CONTROL For as long as people have been engaging in sex they’ve been inventing unique means of preventing it’s frequent result: pregnancy. The most commonly used form of birth control over thousands of years has been good old fashioned ‘coitus interruptus’ or pulling out before the explosion, but there have been many other most interesting approaches. The precursors of modern birth control emerged in Egypt about 300 B.C. There they used mechanical and chemical methods that foreshadow modern diaphragms, cervical caps and spermicides. Their versions included lint pads soaked in honey and acacia tips, and crocodile dung compacted with auyt-gum, both to be inserted into the vagina as a barrier to semen. Some Romans of the 4th century decided that the best way to prevent unwanted pregnancy was to diminish a wife’s desire for sexual intercourse. Specific methods included: mouse dung liniment; swallowing pigeon droppings mixed with oil and wine; or rubbing her loins with the blood of ticks off a wild black bull. Condoms began to come into their own during the eighteenth century. They were usually made of sheep gut, or sometimes fish skin and were originally introduced not for prevention of pregnancy but as a protection against syphilis. Finally, here are a few interesting tidbits of sexual history. • In the 1600s Christians who lived in Turkey had to pay a tax. Tax collectors often required people to show their circumcision in order to determine who was taxable. • John Harvey Kellogg invented corn flakes in 1898 as part of his diet for decreasing sexual desire and masturbation. • The first electrical dildo was sold in 1911. • The term homosexuality is derived not from the Latin homo, “man,” but from the Greek homos, meaning “the same”. • During the 1920s many homosexuals were given electric shock therapy to heal what was then considered a disease. It wasn’t until 1973 that homosexuality was officially removed from the American Psychiatric Association’s list of mental disorders. • Alfred Wolfram set the world kissing record in 1990 by kissing 8,001 women in 8 hours, that’s one kiss every six seconds! • Wilt (the Stilt) Chamberlain is credited with the most famous and well-used penis in sports history. He boasted of having sex with over 20,000 women. • Some male members of Australian tribes still shake each other’s penis as a ritual greeting. • More than 8,000 adult videos are produced every year. That’s almost 22 per day! • In 1999 over $4 billion was spent on phone sex, but more than 50 percent of callers didn’t pay their 900 number bill. vigrx side effects do penis enlarement pills really work penis elargement result free penis enlargment tip cheap penile enlargement pills cheap penis enlagement pills do penile enlargment pills really work free penis enhancement exercise penis enlargment pic before and after

THE RESPIRATORY SYSTEM Intake of oxygen and removal of carbon dioxide are the primary functions of the respiratory system. The respiratory system carries out these life-sustaining acts in close coordination with the circulatory system. Most of the time, we remain blissfully unaware of these automatic functions. The respiratory organs deliver oxygen to the circulatory system. The circulatory system transports the oxygen to all body cells. Oxygen is used by cells to liberate the energy needed for cellular activities. The respiratory system also removes carbon dioxide. Thus, the circulatory system prevents the buildup of this lethal waste byproduct in the body tissues. Irreversible damage to tissues can occur if the respiratory system is halted even for a few minutes. This can cause failure of all the other body systems. The consequence is death! NOSE COMMENCES THE RESPIRATORY PROCESS The respiratory system begins from the nose. It ends in the lungs. The respiratory system is broadly divided into two parts, viz., the upper and the lower respiratory tracts. The upper respirator tract is made up of the nose and the throat (pharynx). The lower respiratory tract includes five organs. They are the voice box (larynx), and the windpipe (trachea), bronchi, bronchioles and the lungs. The trachea splits into the two branches called bronchi. The bronchi further gets divided into further smaller branches called bronchioles. The lungs are a pair of spongy saclike organs. The bronchioles, bronchi, trachea, larynx, pharynx and the nose transport air to and from the lungs. It is the lungs that interact with the circulatory system for delivering oxygen and removing carbon dioxide from the lungs. THE RESPIRATION PROCESS Respiration is a two-pronged process. It involves the respiratory and the circulatory systems. Respiration connotes the coordinated functioning whereby the cells are delivered oxygen and the lethal carbon dioxide is removed. The first phase: The nose begins the first phase of respiration. This is done with inhaling or inhalation (breathing in). The process brings in air along with oxygen from outside the body into the lungs. From the lungs, oxygen goes via the blood vessels to the heart. The heart pumps the oxygen-rich blood to all parts of the body. The first phase of respiration ends with the oxygen moving into the cells from the bloodstream. The second phase: The second phase commences after the oxygen gets into the cells. The cells use the oxygen to produce energy. This independent process is called cellular respiration. It produces the byproduct -- carbon dioxide. The accumulated carbon dioxide now moves from the cells to the bloodstream. Next, the bloodstream transports the carbon dioxide to the heart. Then, the carbon dioxide-laden blood is pumped back to the lungs. The third phase: Again the nose comes into picture during this stage. The lungs push the byproduct to the nose from where it is exhaled or breathed out. This is the final or the third stage when the body gets rid of the carbon dioxide. At the end of the third stage or the entire respiratory cycle another one starts automatically. OTHER FUNCTIONS OF THE RESPIRATORY SYSTEM The respiratory system further regulates the balance of acid and base in tissues. This balancing act is crucial for the normal functioning of cells. It protects the body against disease-causing organisms and toxic substances inhaled with air. The respiratory system also houses the cells that detect smell. Moreover, the respiratory system assists in the production of sounds for speech. THE OLFACTORY NERVE The brownish olfactory nerve is also called olfactory receptors. The olfactory nerve inside the nose is the main nerve of smell. The olfactory region is made up of thick nasal soft mucous membrane. Its brownish color is because of a pigment. The olfactory nerve ends in minute varicose fibers (several small branches). These fibers ultimately conclude in the epithelial cells. Mentionably, the epithelial cells project into the nasal free surface. The olfactory nerve is the first to know of any chemicals that may enter the nasal passages. The receptors immediately trigger off a signal to the brain. This creates the smell perception. THE ESOPHAGUS Esophagus is a muscular tube. The esophagus carries food from the throat to the stomach. The esophagus and the pharynx situated behind the mouth swallow the food and move it to the stomach. The stomach temporarily stores the food, mixes it with digestive juices, and carries out some digestion. The esophagus also holds the stomach contents in place. Actually, this function is carried out by the lower esophageal sphincter. This sphincter is a muscle. It is located at the lower end of the esophagus. THE PHARYNX The pharynx is a passageway for both air and food. The pharynx connects the nose and mouth with the windpipe (trachea) and the food pipe (esophagus). The pharynx is a muscular tube. The pharynx is located within the neck. The pharynx is lined with a mucous membrane. The pharynx is approximately five inches (13 cm) in length. The pharynx lies in the front of the spinal column. The upper portion of the pharynx is known as nasopharynx. The name arises as it begins in the back of the nasal cavity.. The lower part is oropharynx. It points to that area in the back of the mouth. The pharynx ends at the epiglottis. Epiglottis is a flap of cartilage. Epiglottis prevents food from entering the trachea. However, the epiglottis allows the food to enter the esophagus. Two eustachian tubes connect the pharynx to the middle ear. These eustachian equalizes the eardrums air pressure. The pharynx can be infected via the mouth as well as the nose. Sore throat involves pharynx infection (pharyngitis) or throat inflammation. Pharyngitis can be due to infectious mononucleosis, herpes, and viral infections. The viral infections are German measles (rubella), influenza, and common cold. It can also be caused by bacteria like staphylococcal, streptococcal, chlamydial, and diphtherial. These bacteria multiply cause sore throat by multiplying rapidly within the pharynx. Tonsils and Adenoids Among the adults the pharynx contains the tonsils, while among the children the pharynx contains the adenoids. Tonsils: Tonsils are lymphoid tissues at the back of the throat. Tonsils form a tissue ring around the pharynx or the throat. Tonsils are cells. Tonsils are similar to the bloodstream lymphocytes. Tonsils are embedded in fibrous connective tissues. Tonsils are covered by a single epithelium layer. The lymphoid cells are phagocytic. The cells protect the pharynx from bacteria that can cause diseases. Tonsils may become inflamed and chronically or acutely infected. This condition is called tonsillitis. It is generally caused by streptococcus infection. During tonsillitis and streptococcal, the tissues surrounding the tonsils form pus. Then a whitish coat forms over the tonsils which can appear as white specks. This state is called quinsy. When the pharyngeal tonsils become inflamed they become abnormally large. They are called adenoids. Acute cases of tonsillitis are often treated by antibiotics like penicillin. Chronic recurrent tonsillitis may be treated by tonsillectomy (surgical removal of the tonsils). Adenoids: Adenoids are lymphoid tissue at the back of the throat. Adenoids usually shrink and disappear by adolescence. Enlargement of this tissue is common among children. Such a state can interfere with breathing. Symptoms of enlarged adenoids include restless sleep, snoring, breathing via mouth, and a nasal voice. Earlier, these tissues were removed in children. It was thought that inflamed adenoids led to recurrent colds and infections. Nowadays, this condition is recognized as benign. As a result, there are lesser adenoidectomies. THE LARYNX From the pharynx, the inhaled air moves to the larynx. The larynx is about five inches (13 cm) in length. The larynx is located in the central part of the neck. The larynx is made up of several layers of flexible but tough cartilage, a tissue. Mentionably, during puberty the males experience a protrusion of the cartilage. This enlarged prominent extension at the neck is called the Adam’s apple. FUNCTIONS OF THE LARYNX The larynx primarily transports air to the wind pipe (trachea). Besides, the larynx also helps in producing the sounds. The epiglottis -- a leaflike thin tissue portion of the larynx -- further prevents the food from entering the trachea (thus obviating the possibility of choking). Moreover, the cilia cells as well as the mucous membrane of the larynx also filter air. The cilia cells take the airborne substances towards the pharynx where they are swallowed. The epiglottis: The epiglottis stem is attached to the top and the front portions of the larynx. When the epiglottis remains in a vertical position, it acts like a trap door. This happens during the breathing process. But as a person starts swallowing, a reflexive action forces the epiglottis and the larynx to move near each other toward each other. This coming closer of the epiglottis and the larynx forms a protective seal. As a result, the fluids and food are specifically sent towards the food pipe (esophagus). When the reflexive action doesn’t work: What happens when the reflexive action doesn’t function is that the food can enter the larynx. This happens when one eats the meal fats or when one laughs while swallowing. The result is that there will be a recurrent cough impelled choking effect. At times this apparently simple choking effect can even be life-threatening. The cough is the body’s reflexive action to clear the larynx of the impediment. Whenever such choking takes place, someone must thump the back portion between the shoulder blades several times. This will help the person to get over the choking effect. The Heimlich maneuver: The Heimlich maneuver clears the windpipe of obstructions like food or fluid. The first-aid providing person applies thrusts in quick and in upward motion at the patient’s abdomen. The objective is to expel the object stuck at the trachea (windpipe). Standing behind the victim, the person keeps both his arms across the patient’s waist. Then, he places the fist of one hand below the rib cage and a bit above the navel. All the while, he keeps the thumb against the patient’s body. He uses the other hand for holding the fist and for applying pressure. Next, he puts quick pressure on the abdomen. The pressure is put in an inward and an upward motion. This fast recurrent action forces the lung air to get rid of the substance blocking the windpipe. However, in cases where the patient cannot stand still, is overweight, faints following the choking effect, the Heimlich maneuver is done in a different manner. The patient is made to lie face down. The first-aid provider carries on the process with the heel of a hand. Important: Nonetheless, it is important that the person does not put undue pressure on the rib cage. This is especially true when the patient is a child or an elderly person. Too much pressure can break ribs. Pertaining to pregnant woman or overweight people, the first-aid provider must place his hands only on the lower half of the breastbone (sternum) while carrying out the maneuver. In acute choking, tracheotomy (a surgical procedure) is undertaken to carry out bypass of the larynx. This operation brings in air to the trachea. TRACHEA, BRONCHI, AND BRONCHIOLES The trachea is another tube measuring approximately six inches (15 cm). The trachea is located below the larynx. From the larynx the air passes on to the trachea. About 20 sturdy C-shaped cartilage rings constitute the trachea. These rings help to keep the trachea open. In the process, air gets transported unhindered. While the unfastened cartilage is located at the trachea’s back portion, their ends are linked to each other by muscle tissues. Bronchi & bronchioles: The trachea base is situated at the portion where the neck meets the body trunk. At this juncture, the trachea splits into the right and the left bronchi. These bronchi transport air to the right and left lungs respectively. Inside the lungs, these bronchi again break up into smaller tubes -- the bronchioles. In fact, the respiratory system’s cleansing process is carried out by those bronchioles that are situated at the initial part, bronchi, and the trachea. These organs carry out the cleansing process via the mucous membrane linings as well as the ciliated cells. These cilia and the lining push the mucus upward towards the pharynx. Alveoli & capillaries: Alveoli are minute sacs inside the lungs. Most of the alveoli are lung tissues. Alveoli are formed by the bronchioles as they divide several times. The alveoli along with the bronchioles resemble a tree. The alveoli are only 0.02 inches (0.5 mm) in diameter. There are about 150 million alveoli in each lung. The alveoli carry out a dual function. While providing oxygen to the circulatory system, they also remove carbon dioxide from the lungs. The thin elastic alveoli walls expand when air moves into them. The walls collapse to exhale the air. The alveoli remain in clusters like the grapes. Each cluster is surrounded by capillaries. The capillaries are thin-walled and form a dense net of tiny hairs. The alveoli wall air is generally located 0.2 microns away from the blood carried by the capillary. Mentionably, the alveoli have more oxygen concentration then the capillaries. So, oxygen disseminates to capillaries from alveoli. Through the capillaries, oxygen goes to the larger vessels. These vessels then transport the oxygenated blood to the heart. Next, the heart pumps the cleaned blood to the other parts of the body. Macrophages: Among the alveoli are interspersed many macrophages. The macrophages are blood cells. These large white cells act as the last sentinels of the respiratory system among the alveoli. The macrophages segregate the foreign elements which may have passed through the earlier filtration process. This last line of defense ensures that the alveoli are not infected. Carbon dioxide disposal: The cells from across the body dump Carbon dioxide as a waste product. It is dumped in the bloodstream. The blood carries Carbon dioxide into the heart. From the heart, the Carbon dioxide moves to the alveolar capillaries. Notably, the capillaries have more concentration of carbon dioxide than the alveoli. So, carbon dioxide gets diffused into the alveoli from the capillaries. When a person exhales, the Carbon dioxide is forced back via the respiratory routes. The gas is then thrown outside the body.
