The omentum is a large fold of peritoneum that hangs down from the stomach, covering the intestines. It's full of fat and blood vessels, acting like a protective apron. Think of it as the body's "abdominal policeman." It helps to isolate infections and promote healing. There are two main parts: the greater omentum and the lesser omentum. It's like a versatile tool belt containing the resources needed for abdominal protection and repair.
