AP BIOLOGY

Detailed explanation-1: -The appendix has no known function in humans. Evidence suggests that our evolutionary ancestors used their appendixes to digest tough food like tree bark, but we don’t use ours in digestion now.

Detailed explanation-2: -The appendix, notorious for its tendency to become inflamed or even rupture, has historically been viewed as a vestigial organ with no real function. But new research supports the idea that the appendix may indeed serve a purpose: to protect beneficial bacteria living in the gut.

Detailed explanation-3: -The appendix has been found to play a role in mammalian mucosal immune function. It is believed to be involved in extrathymically derived T-lymphocytes and B-lymphocyte-mediated immune responses. It is also said to produce early defences that help prevent serious infections in humans.

Detailed explanation-4: -The appendix may be the most commonly known useless organ.

Detailed explanation-5: -Your appendix doesn’t directly help with digestion. It’s been unclear what role the appendix has in the body, and removal of the organ doesn’t appear to have any negative health consequences.
