Large intestine

section of the alimentary canal which ends at the rectum (Anatomy)

The large intestine, an organ which is now more commonly referred to by its Greek name, the colon, is the last part of the digestive system: the final stage of the alimentary canal in vertebrate animals. Its function is to absorb the remaining water from indigestible food matter, stores these unusable food matter (wastes) and then eliminates the wastes from the body.
