Accepted Answer

The two major body cavities are the dorsal cavity, which contains the cranial and spinal cavities, and the ventral cavity, which contains the thoracic and abdominopelvic cavities. The thoracic and abdominal cavities are subdivisions of the ventral cavity, and the pelvic cavity is also a subdivision of the ventral cavity but not a major body cavity on its own. The mediastinum and pleural cavities are subdivisions of the thoracic cavity.
