The appendix is the organ that can be considered vestigial in humans but functional in other mammals. The appendix is a small, thin, finger-shaped pouch attached to the large intestine. In humans, the appendix does not appear to have any significant function, but in other mammals, it is used to digest cellulose, a tough carbohydrate found in plants. Therefore, in humans, the appendix is considered a vestigial organ, which means it no longer serves a useful function. However, in some cases, the appendix can become infected, leading to a condition called appendicitis, which requires medical attention.
