What it is and what it does

The abdomen is the portion of the trunk behind the ribs, as far as the pelvis. It has no bones on its sides: its wall is muscular. Inside sit the stomach, intestines, liver, kidneys, spleen and urinary bladder. The underline, from the chest toward the flank, "rises" more or less depending on the breed.

Worth remembering

Inside sit the stomach, intestines, liver, kidneys, spleen and urinary bladder.
