The colon may be divided into the cecum, the ascending colon, the transverse colon, the descending colon, the sigmoid colon and the rectum. The large intestine (colorectum) begins at the cecum, a pouch approximately 2–3 inches long. Ileal contents empty into the cecum through the ileocecal valve. The appendix extends from the base of the cecum.
