The greater omentum is a fold of fatty tissue that hangs from the stomach and drapes over much of the intestines. It contains blood vessels, immune cells, and fat deposits that support its protective functions within the abdominal cavity.
Often called the “policeman of the abdomen,” the omentum can respond to inflammation and infection by moving toward affected areas and adhering to nearby tissues. It helps contain local infections, supports immune activity, and contributes to tissue repair. It also plays a role in fat storage and metabolic regulation.
This remarkable structure is more than a protective layer of fat — it is an active participant in abdominal immunity and inflammation.
