Abdomen

This is the region of the body between the chest and the pelvis.

Peters 2007, p4

The abdominal cavity (area of the abdomen) is bounded

• by the ribs and diaphragm above, and
• by the pelvis below...
• with the spine and abdominal muscles forming the back, side, and front walls

The abdomen contains the liver, stomach, intestines, spleen, pancreas, and kidneys.
In the lower abdomen, enclosed by the pelvis, are the bladder, rectum, and, in women, the uterus and ovaries.
