A. AppendixExplanation
Why we have an appendix is kind of a fuzzy issue. Some scientists now think that it's a repository for "good" bacteria. What we do know is that appendices can become infected. If they become infected, they must be surgically removed or they can rupture. If they rupture, the infection spreads throughout the body and can kill you. People who've had their appendix removed can live normal, healthy lives without it. So...do you really need an appendix? No.Rate this question:
