Does the appendix have a function HowStuffWorks
The appendix has no known function in present-day humans, but it may have played a role in the in humans of earlier times. The appendix is also called the vermiform appendix because of its wormlike (“vermiform”) shape. Your appendix is located in your lower right abdomen, attached to the large intestine. Just past the ileocecal valve the gateway between the small and large intestine, is the cecum a bulbous mass located at the bottom of the ascending colon. The appendix is a vermiform (worm shaped) organ that hangs off the end of your cecum. In most people it is about 65 cm long. At one time the appendix was thought to be a vestigial organ left over from the days of eating large amounts of plant matter, we now understand the appendix probably plays an important role in our immune system due to its rich supply of lymphocytes better known as B-cells, T-cells and natural killer cells. There are many different types of T-cells, but one of the best known to us are memory T-cells as their name suggests, they are responsible for our immunity to certain diseases through vaccinations. B-cells make the antibodies that fight antigens (foreign cells). Natural killer cells attack viruses and tumor cells. Although, current knowledge of the role of our appendix is based on well educated guesses, here is what we know:: our appendix may have played a role in helping our distant relatives digest plant matter a mainstay of their ancient diet by storing additional digestive enzymes. Scientists base this knowledge on the comparison between the human appendix and the koala bear appendix. The appendix is rich in lymphocytes as stated above. The appendix -- an organ barely 9 inches long -- causes much debate among medical professionals. In fact, doctors have trouble deciding if the appendix has any use to the body at all. While everyone agrees that the appendix can be removed without causing any adverse health consequences to the patient, some physicians and researchers believe that the appendix does serve a function as part of the immune system. Others feel that the appendix is a, a remainder from the time when humans regularly dined on tree bark and needed an additional organ to break down the roughage. Along with the disagreement over the true function of the appendix, there is no consensus if humans will always have this organ. Some doctors feel that the evolution of the human body will lead to the demise of the appendix, while others believe that the appendix will remain in the body, continuing to do whatever it does. Prophylactic appendectomies for astronauts?
How about for international travelers? If the appendix has no purpose, yet is potentially subject to all of these dangerous -- even life threatening -- conditions, then why can't we simply have a doctor remove our appendix as a preventative procedure? With no clear determination of what the appendix does, there's no agreement on whether prophylactic appendectomies -- appendectomies performed to avoid possible future medical emergencies -- are medically appropriate. For years rumors have circulated that astronauts had their appendixes removed before space travel to avoid a potential medical emergency while in orbit. For similar (yet more earthbound) reasons, many people wonder whether they should have theirs removed before boarding an international flight. There's no truth to the rumor about astronauts, and most physicians do not recommend preventative appendectomies for world travelers either. Seven percent of the general population will have their appendix removed at some point in their lives. Given these low odds, and the fact that most will not pay for a prophylactic appendectomy, they are generally not considered for the healthy traveler. Prophylactic appendectomies are occasionally performed if the patient is undergoing other abdominal surgery. For instance, if the patient has an ovarian cyst removed or a hysterectomy, the doctor may perform an appendectomy at the same time. The reason for this is twofold. If the patient has a history of abdominal pain, such as with endometriosis, that pain can mask the symptoms of appendicitis. Additionally, recovering from abdominal surgery isn't pleasant, and by removing the appendix at the same time as conducting other surgery, you minimize the likelihood of additional surgery. Extending from the inferior end of the large intestine’s cecum, the human appendix is a narrow pouch of tissue whose resemblance to a worm inspired its alternate name, vermiform (worm-like) appendix. It is located in the right iliac region of the abdomen (in the lower right-hand abdominal area), measuring about four inches long and roughly a quarter of an inch in diameter. The appendix is not a vital organ and medical researchers still debate its exact function in our bodies. One hypothesis suggests that it is a vestigial remnant of a once larger cecum. This larger cecum would have been used by vegetarian ancestors to digest cellulose from plants. Supporters of this hypothesis therefore conclude that the appendix no longer serves any purpose for us. Another hypothesis suggests that the appendix acts as a storage area for beneficial bacteria during times of illness.
Beneficial bacteria living in the appendix could survive being flushed out of the large intestine by diarrhea. The appendix would therefore help a person to recover more rapidly from illness by enabling the bacteria to re-colonize the intestines after the illness has passed. Doctors typically remove an appendix if it becomes inflamed, and even a healthy appendix may be removed during abdominal surgeries such as a hysterectomy. A doctor’s justification for this removal is that the appendix is susceptible to bacterial infections that lead to, a fairly common and dangerous inflammation of the appendix. Often one of the first signs of appendicitis is pain and tenderness near the navel, often growing sharper and spreading downward into the lower right abdomen. The pain can grow quite severe over the course of a few hours, so much so that it may be impossible to get comfortable or to move without pain. Applying pressure to the area will commonly cause pain that can sharpen after releasing the pressure (a phenomenon called “rebound tenderness”), though this is not always the case. Additional common symptoms include nausea, vomiting, fever and others. Tenderness and growing pain in the right abdomen that is noticeable enough to cause considerable discomfort during movement or at rest warrants medical attention in order to reach a diagnosis and receive any necessary treatment. Untreated appendicitis can lead to the rupture of the appendix, a serious medical emergency wherein fecal matter leaks out of the cecum. Left untreated, the bacteria-laden fecal matter spreads throughout the abdominal cavity, where the bacteria begin to digest the peritoneum that lines the cavity. The infection and inflammation of the peritoneum, known as peritonitis, is a severely painful and potentially fatal consequence of appendicitis.
