The appendix is a small, tube-like organ attached to the first part of the large intestine. It is located in the lower right part of the abdomen. It has no known function. A blockage inside of the appendix causes appendicitis. The blockage leads to increased pressure, problems with blood flow, and inflammation. If the blockage is not treated, the appendix can burst and spread infection into the abdomen. Appendicitis is a medical emergency. It is almost always treated with surgical removal of the inflamed appendix. Although anyone can develop appendicitis, most often it occurs in people between the ages of 10 and 30. Scientists used to believe that the appendix had no useful role in modern humans. However, more recently it has been suggested that the appendix may contain a reservoir of good bacteria and that, in early childhood, the immune tissues in the appendix are important in the development of the immune system. Despite all this it seems that removing the appendix leaves no ill effects.
