Cecum: This first section of your large intestine looks like a pouch, about two inches long.

What is the length of Caecum?

The cecum exists as a large pouchlike cul-de-sac in the right iliac fossa and feeds the ascending colon. Its diameter is greater than its length; the adult cecum measures approximately 6 cm in length and 7.5 cm in width.

How long is the colon?

The entire colon is about 5 feet (150 cm) long, and is divided into five major segments. The rectum is the last anatomic segment before the anus. The ascending and descending colon are supported by peritoneal folds called mesentery.
