Sigmoid colon is the section of the colon that leads to the rectum and anus. It makes an S-shaped curve. The colon's other segments are the cecum, ascending colon, transverse colon, and descending colon, with the entire length typically about six feet.
The sigmoid colon is the part of the colon, or large intestine, that is located right before the rectum. It looks like an S-shaped curve.
Digested food comes from the small intestine, enters the large intestine at the cecum, moves up the ascending colon, across the transverse colon, and down the descending colon, and then into the sigmoid colon and rectum. All the while, water is removed from the stool. The average colon is about six feet long, including all parts.
