Do You Really Need Your Appendix?

For years, doctors have debated the purpose of the appendix, a narrow pouch extending from the cecum of the large intestine. Many believe that it is a vestigial remnant of some previous organ or structure and that it no longer has a purpose in human anatomy. Recently, investigators at Duke University Medical School published a study suggesting that the appendix actually protects the human body from the effects of diseases like cholera and dysentery. According to their research, the pouch shelters important intestinal bacteria that can repopulate the digestive system even after it is completely wiped out by disease.
