The omentum is a membranous double layer of fatty tissue that covers and supports the intestines and organs in the lower abdominal area.
The omentum is split into two segments called the greater and lesser omentum. The greater omentum is a mass that sits in front of the stomach. The lesser omentum covers the liver. Both become easy repositories for fat storage.  Definition of OMENTUM. : a fold of peritoneum connecting or supporting abdominal structures (as the stomach and liver); also: a fold of peritoneum free at one end. — omen·tal \-ˈmen-təl\ adjective. ADVERTISEMENT. Medical Definition of OMENTUM. : a fold of peritoneum connecting or supporting abdominal structures (as the stomach and liver)—see greater omentum, lesser omentum. Omentum: A sheet of fat that is covered by peritoneum. The greater omentum is attached to the bottom edge of the stomach and hangs down in front of the intestines. Its other edge is attached to the transverse colon. The lesser omentum is attached to the top edge of the stomach and extends to the undersurface of the liver. gastrohepatic omentum. the part of the lesser omentum attached to the liver. greater omentum. the double fold of peritoneum derived from the dorsal mesogastrium that extends from the greater curvature of the stomach over the floor of the abdomen like an apron; poorly developed in the horse and well developed in ruminants. The portion of the omentum that is suspended from the greater curvature of the stomach and covers the intestines like an apron. It is the largest of the folds of the peritoneum. It dips in among the folds of the intestines and is attached to the transverse colon and mesocolon The omentum as fatty tissue that insulates the abdominal organs. The omentum is a membranous double layer of fatty tissue that covers and supports the intestines and organs in the lower abdominal area. The omentum is made up of the greater omentum which is an important storage for fat deposits and the lesser omentum which connects the stomach and intestines to the liver. Milky spots on the greater omentum contain white blood cells that assist immunity by removing cellular debris.  greater omentum.

It is made up of two layers of fatty tissues and both supports and covers the organs and intestines found in this area of the body. In contrast with the greater omentum, the lesser omentum has the distinction of being very thin. It is continuous with the peritoneum layers that cover the postero-inferior and antero-superior stomach surfaces as well as the first portion of the duodenum. The greater omentum (also the great omentum, omentum majus, gastrocolic omentum, epiploon, or, especially in animals, caul) is a large apron-like fold of visceral peritoneum that hangs down from the stomach. It extends from the greater curvature of the stomach, passing in front of the small intestines and reflects on itself to ascend to the transverse colon before reaching to the posterior abdominal wall. The greater omentum is larger than the lesser omentum which hangs down from the liver to the lesser curvature. The common anatomical term epiploic derives from epiploon from the Greek epipleein meaning to float or sail on, since the greater omentum appears to float on the surface of the intestines
