abdomen (s) (noun), abdomens (pl)
1. The part of the human body that contains all of the structures between the chest and the pelvis: The abdomen, or belly, is anatomically separated from the chest by the diaphragm, the powerful muscle that spans the body cavity, just below the lungs.
2. That section of the body that lies between the lower thorax (chest) and the pelvis: The abdomen is the area of the body just below the diaphragm which contains the largest cavity in the body.

Also called belly (popular), venter, and stomach (incorrect). Derived from abdo, abdere, "to hide", and so probably originally referred to the "hidden part of the body".

Abdomen [Lat. from abdo, to hide.] A cavity commonly called the lower venter or belly: It contains the stomach, guts, liver, spleen, bladder, and is within lined with a membrane called peritoneum.
