Front View of the Appendix
The appendix sits at the junction of the small intestine and large
intestine. It’s a thin tube about four inches long. Normally, the appendix sits
in the lower right abdomen.
The function of the appendix is unknown. One theory is that the appendix
acts as a storehouse for good bacteria, “rebooting” the digestive system after
diarrheal illnesses. Other experts believe the appendix is just a useless
remnant from our evolutionary past. Surgical removal of the appendix causes no
observable health problems.
