coelom
The main cavity within the body of all animals higher than the cnidarians and certain primitive worms, lying between the inner digestive tube and outer body wall. It is formed by the splitting of the embryonic mesoderm into two layers. In mammals it forms the peritoneal, pleural, and pericardial cavities.
