Questions & Answers

Q: How has the appendix evolved in mammals?

The appendix has evolved in mammals at least 29 times, indicating that it provides some evolutionary advantage.

Q: What is the role of the appendix in immunity?

The appendix houses immune cells and acts as a reservoir for good gut bacteria, suggesting it plays a role in the body's immune response.

Q: Why might the appendix provide emergency rations of gut bacteria?

During cases of extreme diarrhea, the appendix may provide a fresh population of gut bacteria to maintain proper digestion.

Q: Does removal of the appendix have any implications?

A study found that patients without an appendix were twice as likely to develop a severe bacterial infection, suggesting the appendix may help prevent infections.
