It is from one to six inches in length, and ofthe size of a goose-quill. 250. The colon is divided into three parts — the ascending,transverse, and descending. The ascending colon passesupward from the right haunch-bone to the under surface ofthe liver. It then bends inward, and crosses the upper partof the abdomen, below the liver and stomach, to the left side,under the name of the transverse colon. At the left side, itturns, and descends to the left haunch-bone, and is called thedescending colon. Here it makes a peculiar curve upon itself,which is called the sigmo id flexure.

The rectum is the termination of the large large intestine has three coats, like the stomach andsmall intestine. The longitudinal fibres of the muscular coatare collected into three bands. These bands are nearly onehalf shorter than the intestine, and give it a sacculatedappearance, which is characteristic of the ccecum and colon. 252.
