You may have heard that astronauts have their appendix removed before leaving Earth. After all, people say you can live without this organ because it serves no purpose, but how much truth is there in this belief?

Let’s start by locating it. The appendix is a small, finger-shaped pouch located where the small intestine joins the large intestine, in the cecum.

If left untreated, it can become life-threatening.
