Appendix

What is the appendix?

The appendix is a small finger-shaped organ that connects with your large bowel (colon) by a small opening. In most people, the appendix sits in the lower right abdomen just above your hip bone.

The appendix and the large bowel have a similar structure. Both the appendix and the large bowel are lined by cells called goblet cells. These cells produce mucin which helps food move smoothly through your large bowel. The appendix also contains cells that are a part of your immune system and these cells help to form a protective barrier between your body and the inside of the bowel.

Acute appendicitis is a very common condition caused by inflammation of the appendix. It can affect people of any age but it is more common in children and young adults.
