The abdominopelvic cavity is part of which larger body cavity?

• A. Dorsal cavity
• B. Ventral cavity
• C. Cranial cavity
• D. Spinal cavity

Answer: (B)

The question focuses on how the body’s cavities are organized. The abdominopelvic cavity sits in the ventral (anterior) cavity, which also includes the thoracic cavity and is separated from it by the diaphragm. The dorsal (posterior) cavity, in contrast, contains the cranial cavity (housing the brain) and the spinal cavity (housing the spinal cord). Since the abdominopelvic region is located toward the front and is part of the ventral cavity, that is the larger cavity it belongs to.
