10 Foods That Look Like The Body Parts They Benefit The Most

Appendix

The appendix is a tiny pouch attached to the cecum, which is a part of the large intestine. It is believed to have played a role in the digestive process for early humans, but today, it can be easily removed with the help of an appendectomy, usually in the case of appendicitis or an inflamed appendix, which affected an estimated 1.77 crore people in 2019, as per a studypublished in the World Journal of Surgery.

For a long time, the appendix has been considered a vestigial organ, until recently, when studies indicated that it may act as a ‘safe house’ for good bacteria in the digestive system. More recent research, published in Comptes Rendus Palevol, suggests that it might be involved in immunity due to its link to immune tissue in the cecum.

Tonsils

Tonsils are a part of the immune system, located at the back of the throat. They help protect against infections, especially during childhood, but are also prone to turning against the body, leading to various health complications.
