Full Answer

The omentum, found in the lower abdominal area, is a membranous double layer containing fatty tissues that cover and support intestines and other organs found in the lower abdomen. It has two parts: the lesser omentum, which connects the stomach and intestines to the liver, and the greater omentum, which stores fat deposits.

The greater omentum is also called the omentum majus, the gastrocolic omentum, the epiploon or, when referring to animal anatomy, the caul. The greater omentum starts from the greater curvature of the stomach and passes by the small intestines. Ascending the transverse colon, it ends at the posterior abdominal wall. The greater omentum is composed of fat, blood vessels, cellular tissues and lymphatic tissues, which are essential to the body's immune system. It phagocytizes the inflammation process and isolates injuries and lesions in the abdominal wall.

The lesser omentum is also called the small omentum or gastrohepatic omentum. It is found in a double layer that begins at the stomach's lesser curvature and the start of the duodenum and extends to the liver. Surgeons consider omentum evaluation a crucial diagnostic process during CT scans.
