abdomen

In human anatomy, this term is the precise medical designation for the belly area. While "stomach" is frequently used in casual conversation to refer to the entire midsection, "abdomen" is the correct term for the anatomical region containing multiple organs beyond just the stomach, such as the liver and intestines.

In entomology and zoology, the term describes a specific structural segment of an arthropod's body. It is distinguished from the cephalothorax or thorax by its position at the rear of the organism and its specialized functions related to digestion and reproduction.
