The ventral body cavities are the two main anterior cavities: the thoracic cavity and the abdominopelvic cavity. The thoracic cavity houses the heart and lungs and includes the pleural cavities around the lungs and the pericardial cavity around the heart. The abdominopelvic cavity comprises the abdominal and pelvic regions. So naming the thoracic cavity and the abdominopelvic cavity correctly identifies the ventral cavities as a whole. The cranial and vertebral cavities are dorsal; the pleural and pericardial cavities are subdivisions within the thoracic cavity, and the abdominal and pelvic cavities are subdivisions within the abdominopelvic cavity.
