Colon. Illustration of the human digestive system, highlighting the large intestine (blue) or colon. The colon is a segmented muscular tube, about 1.3 metres long and 6.5cm wide. When the contents of the small intestine (seen here within colon) enter the colon, the food has already been digested and a liquid form remains. The colon removes water and some minerals from this liquid, leaving behind faeces, which then pass to the rectum (lower centre). The wall of the colon produces a rich mucus that protects its tissue and lubricates the semi-solid contents. Also seen here are the liver (top left), stomach (top right) and pancreas (under stomach).
