coelom


coelom
Body cavity characteristic of most multicellullular animals (all coelomates). Arises within the embryonic mesoderm, that is thereby subdivided into somatic mesoderm and splanchnic mesoderm, and is lined by the mesodermally-derived peritoneum. May be secondarily lost and it is unclear whether it evolved once or several times.
