ABDOMINAL CAVITY

The abdominal cavity extends from the lower border of the ribs to the pelvis. The abdominal wall is made up of muscle, layers of connective tissue, and fat and is lined by a thin double layered membrane called the periosteum. The abdominal cavity contains all of the organs of the digestive system and the genitourinary system.
