Colon

(KOH-lun) The longest part of the large intestine, which is a tube-like organ connected to the small intestine at one end and the anus at the other. The colon removes water and some nutrients and electrolytes from partially digested food. The remaining material, solid waste called stool, moves through the colon to the rectum and leaves the body through the anus.

The long, coiled, tube-like organ (also known as the large bowel or large intestine) that removes water from digested food. The remaining material, solid waste called "stool," moves through the colon and the rectum and leaves the body through the anus. Parts of the colon include the cecum, ascending colon, transverse colon, descending colon, and sigmoid colon. The average colon is about six feet long.
