The vermiform (wormlike) appendix is located anatomically in the right lower quadrant of the abdominopelvic cavity at the most inferior end of the ascending colon.

The appendix has been studied for decades by researchers trying to determine the organs function. One long standing theory is that when humans consumed raw meat as food the appendix assisted with digestion. Another theory is that it played a role in body defenses acting in concert with the immunologic system.

Present day researchers generally agree that the organ has absolutely no appreciable function whatsoever and only serves as a structure that houses bacteria and toxins. The body can function quite well without the appendix.

The appendix really does not have a job and we can certainly live without it. The appendix is tissue that extends from the large intestine and is a little over three inches long. The problem with the appendix is that it can become inflamed. When this happens it is called appendicitis. Surgery needs to be performed as soon as possible to prevent the appendix from bursting and spilling toxins into the body, which can be very dangerous. Appendicitis can occur when it becomes blocked or infected.

In the U.S., 1 in 15 people will get appendicitis. Although it can strike at any age, appendicitis is rare under age 2 and most common between ages 10 and 30.

Appendix in anatomy refers to an organ present in many higher animals such as apes and rodents and some other animals located near the junction of small and large intestine. Appendix ins present in humans also, but it has no known function. It is believed that the appendix lost its utility for humans at some stage during the process of evolution, but the organ itself remained. Some new studies indicate the possibility of appendix in humans serving the purpose of harbouring and protecting certain bacteria that beneficial in the working of human colon.

In other animal appendix helps in digestion.
