The omentum is one of the important parts of the peritoneum which is the lining in the abdominal wall. The omentum is also known as the policeman of the abdominal area. This is a very important part of the body that is situated in the areas of the lower abdomen. Consisting of two different and doubled-up layers of fatty tissue, the omentum acts as a support for the intestines and stomach that falls under the lower abdominal area. One of the main functions of the omentum is to ensure that the fat deposits are stored in the right place. It also assists in supporting the organs such as the stomach and the large intestines. There are two parts of the omentum: the greater and the lesser omentum.
