Concept: 13 - What is the appendix?



The appendix is a small, tube-shaped pouch that is attached to the large intestine, specifically to the lower right part of the abdomen. It is a vestigial structure, which means that it has lost its original function over the course of evolution.

While the exact function of the appendix is not well understood, it is believed to have played a role in the digestive system of our distant ancestors. However, in modern humans, the appendix is no longer necessary for digestion and can be removed without any significant impact on health.

Despite its vestigial nature, the appendix can become inflamed or infected, a condition known as appendicitis, which can cause severe pain and require surgical removal. In some cases, if appendicitis is not treated promptly, the appendix can rupture, leading to a potentially life-threatening infection.
