In human anatomy, the appendix (or vermiform appendix; also cecal appendix) is a blind ended tube connected to the cecum, from which it develops embryologically. The cecum (or caecum) is a pouch-like structure of the colon. The appendix is near the junction of the small intestine and the large intestine. It is also able to be removed.
Why do humans have an appendix?
Our appendix is the vestigial remnant of an intestinal pouch used to ferment the hard-to-digest plant diets of our ancestors. (Orangutans and grazing animals have a large hollow appendix instead of the tiny, wormlike one that we possess.) An appendix is simply a bad thing to have. It is certainly not the product of intelligent design: how many humans died of appendicitis before surgery was invented?
