he appendix is a long narrow tube (a few inches in length) that attaches to the first part of the colon. It is usually located in the lower right quadrant of the abdominal cavity. The appendix produces a bacteria destroying protein called immunoglobulins, which help fight infection in the body. Its function, however, is not essential. People who have had appendectomies do not have an increased risk toward infection. Other organs in the body take over this function once the appendix has been removed.
