The abdominal cavity
is the body cavity
of the human body (and animal bodies) that holds the bulk of the viscera
and which is located below (or inferior
to) the thoracic cavity
, and above the pelvic cavity
. It is a part of the abdominopelvic cavity
Organs of the abdominal cavity include the stomach, liver, gallbladder, spleen, pancreas, small intestine, kidneys, and large intestine.
The abdominal cavity is lined with a protective membrane termed the peritoneum. The kidneys are located in the abdominal cavity behind the peritoneum, in the retroperitoneum. The viscera are also covered, in the front, with a layer of peritoneum called the greater omentum (or omental apron).
