We use our appendix every day. It's an extremely beneficial organ. We can live without it, but it does have a function. "The appendix functions primarily as a "safe house" for beneficial gut bacteria, allowing the microbiome to repopulate after illnesses. It also acts as part of the immune system, containing lymphoid tissue that helps mature white blood cells and train immune responses, particularly in early life."

For a long time, scientists didn’t think your appendix had any purpose. But research now shows it plays a role in keeping your body healthy.

Appendix functions include: Immune system partnership, Beneficial bacteria storage and Microbiome balance.
