Appendix - Feel It In Your Gut

We don't know what the appendix does! This vestigial organ is often called "useless" but we prefer “mysterious,” as we don’t really know how it works. Some think the appendix, located at the bottom right of the intestine, doesn’t do anything. Others think it helps good bacteria populate the gut. Most of us don’t think about the appendix at all until it needs to get removed. Then we miss it terribly.
