Lower GI tract

Anatomical Information about Lower GI tract

The last part of the GI tractócalled the lower GI tractóconsists of the large intestine and anus. The large intestine is about 5 feet long in adults and absorbs water and any remaining nutrients from partially digested food passed from the small intestine. The large intestine then changes waste from liquid to a solid matter called stool. Stool passes from the colon to the rectum. The rectum is located between the last part of the colonócalled the sigmoid colonóand the anus. The rectum stores stool prior to a bowel movement. During a bowel movement, stool moves from the rectum to the anus.
