Which cavity houses the heart and lungs?

• A. Abdominal cavity
• B. Thoracic cavity
• C. Cranial cavity
• D. Ventral body cavity

Answer: (B)

The thoracic cavity is the correct answer because it is the anatomical space within the rib cage that contains critical organs such as the heart and lungs. This cavity is bordered superiorly by the neck, inferiorly by the diaphragm, and laterally by the ribs, providing a protective environment for these vital organs. Specifically, the heart is located in a region of the thoracic cavity known as the mediastinum, while the lungs occupy the pleural cavities on either side. The abdominal cavity contains organs associated with digestion, the cranial cavity houses the brain, and the ventral body cavity is a broader category that encompasses both the thoracic and abdominal cavities. Therefore, while the ventral body cavity is a correct descriptor of where the thoracic cavity is located within the larger structure of the body, the more specific answer addressing the location of the heart and lungs is the thoracic cavity itself.
