The part of the body between the chest and pelvis that contains many major digestive, urinary, reproductive, and other internal organs.
The abdomen contains organs and structures including the stomach, small and large intestines, liver, gallbladder, pancreas, spleen, kidneys, and parts of the urinary and reproductive systems.
The abdominal cavity is separated from the chest cavity primarily by the diaphragm.
QUICK FACT
The kidneys are located toward the back of the abdomen, rather than in the central abdominal cavity.
COMMONLY CONFUSED WITH
