Question: What is the main purpose of Apandix in human body? I wana know about apandix what is the function in our body, is it necessory?

Answer: In human anatomy, the vermiform appendix (or appendix, pl. appendices) is a blind ended tube connected to the cecum (or internationally, "caecum"). It develops embryologically from the cecum. The term vermiform comes from Latin and means "wormlike in appearance". The cecum is the first pouch-like structure of the colon. The appendix is near the junction of the small intestines and large intestines.\n\nCurrently, the function of the appendix, if any, remains controversial in the field of human physiology. It has been known to cause the ability to process bark, leaves and other things of that nature.\n\nThere 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.\n\nOne explanation has been that the appendix is a vestigial structure with no current purpose.[citation needed] The appendix is thought to have descended from an organ in our distant herbivorous ancestors called the cecum (or caecum). The cecum is maintained in modern herbivores, where it houses the bacteria that digest cellulose, a chemically tough carbohydrate that these animals could not otherwise utilize. The human appendix contains no significant number of these bacteria, and cellulose is indigestible to us. It seems likely that the appendix lost this function before our ancestors became recognizably human.
