Artwork showing the anatomy of the human colon or large intestine. The colon has no digestive function but is concerned with the absorption of water & electrolytes from the residue of digestion. It consists of 4 sections: the ascending (left), transverse (top), descending (right) and sigmoid (bottom). The sigmoid colon joins with the rectum. The ascending & transverse sections are triangular in cross-section, due to three bands of longitudinal muscle, the teniae coli, which run the length of the organ, from the base of the appendix (tail-like at bottom left) to the rectum. The teniae help to form haustra, the compartment-like pouches along its length.
