There are actually more than 6. I believe they would be the cecum, ascending colon, hepatic flexure, transverse colon, colic (or splenic) flexure, descending colon, and sigmoid colon.

The large intestines is also known as the colon. The colon is divided into four sections called the ascending colon, the transverse colon, the descending colon, and the sigmoid colon.

The Sigmoid Colon is the fourth colon..

The sigmoid colon is the last section of the colon (large intestine).
