- Human abdomen
The human abdomen (from the
Latinword meaning "belly") is the part of the body between the pelvisand the thorax. Anatomically, the abdomen stretches from the thorax at the thoracic diaphragmto the pelvis at the pelvic brim. The pelvic brim stretches from the lumbosacral angle (the intervertebral diskbetween L5 and S1) to the pubic symphysisand is the edge of the pelvic inlet. The space above this inlet and under the thoracic diaphragm is termed the abdominal cavity. The boundary of the abdominal cavity is the abdominal wall in the front and the peritoneal surface at the rear.
Functionally, the human abdomen is where most of the
alimentary tractis placed and so most of the absorption and digestion of food occurs here. The alimentary tract in the abdomen consists of the lower esophagus, the stomach, the duodenum, the jejunum, ileum, the cecumand the appendix, the ascending, transverse and descending colons, the sigmoid colonand the rectum. Other vital organs inside the abdomen include the liver, the kidneys, the pancreasand the spleen.
abdominal wallis split into the posterior (back), lateral (sides) and anterior (front) walls.
