False-colour X-ray of the human appendix and colon. The appendix, a narrow finger-shaped tube of the intestine, about 9 centimetres long in adults, is seen curled at bottom. In structure it has a thick wall, narrow cavity, and a lining similar to the large intestine to which it is attached. At centre is the colon of the large intestine. The appendix is located near the point where the small intestine (centre right and top right) leads into the colon. The appendix has no known function. The colon functions to absorb water and minerals from food that has already been digested. This is a gas- contrast X-ray image which has been false-coloured by computer.
