Ascending Colon

The ascending colon is about 5 in. (13 cm) long and lies in the right lower quadrant. It extends upward from the cecum to the inferior surface of the right lobe of the liver, where it turns to the left, forming the right colic flexure, and becomes continuous with the transverse colon. The peritoneum covers the front and the sides of the ascending colon, binding it to the posterior abdominal wall.
