Question

Why does the human body have an appendix if the appendage has no known function?​

Answer 1

The appendix is a vestigial organ that has no known function in the human body. Its specific purpose is still uncertain, but it may play a role in immunity and have an endocrine function in fetuses. It may also serve as a storage for the colon's normal bacteria and help repopulate the colon if necessary.

Step-by-step explanation:

The appendix is a vestigial organ in the human body. Although its specific function is still uncertain, it was thought to play a role in immunity. In addition, it is believed to have an endocrine function in fetuses, releasing hormones needed for homeostasis. Some biologists speculate that the appendix may also store a sample of the colon's normal bacteria, which can help repopulate the colon with bacteria if illness or antibiotic medications deplete them.

Appendicitis, or infection and inflammation of the appendix, is a common medical problem that is typically resolved through surgical removal of the appendix. People who have their appendix removed do not suffer any ill effects, indicating that the organ is dispensable.

Answer 2

No one is completely sure what the function of the appendix is. Some think it is a digestive organ, others have suggested that it has some role in our immune system that is slightly different from the rest of the digestive tract.

But studies show as humans evolved, they started to include more easily digestible food in their diet and the appendix eventually lost it function.
