The thoracic cavity is the what subdivision of the ventral body cavity?

• A. Superior
• B. Inferior
• C. Lateral
• D. Posterior

Answer: (A)

The ventral body cavity is organized into two main compartments, with the thoracic cavity sitting above the diaphragm. Since the diaphragm forms the boundary between the thoracic cavity and the abdominopelvic cavity, the thoracic cavity is the superior subdivision of the ventral cavity. Terms like lateral or posterior describe directions, not divisions, and inferior would place you below the diaphragm in the abdominalpelvic region. So the thoracic cavity is the upper, or superior, part of the ventral cavity.
