How does appendix function in our body?
Medical literature shows that the appendix is not generally credited with significant function. The appendix is rich in infection-fighting lymphoid cells, suggesting that it might play a role in the immune system. Whether or not the appendix has a function, it is routinely removed without any ill effects or side effects. Some experts believe that the appendix was used for digesting leaves as primates. Over time, we have eaten less vegetables and have evolved, over millions of years, for this organ to be smaller to make room for our stomach. There have been cases of people who have been found, usually on laparoscopy or laparotomy, to have a congenital absence of their appendix. There have been no reports of impaired immune or gastrointestinal function in these people. The most common explanation is that the appendix is a vestigial structure with no absolute purpose.
