The lungs are housed in which cavities?

• A. Abdominopelvic cavity
• B. Pleural cavities
• C. Pericardial cavity
• D. Cranial cavity

Answer: (B)

Lungs are housed in pleural cavities, two thin spaces that surround each lung within the thoracic cavity. Each lung sits inside its own pleural cavity, lined by two layers of pleura—the visceral pleura on the lung surface and the parietal pleura lining the chest wall. The small volume between these layers, filled with pleural fluid, allows smooth expansion and recoil during breathing. The other options don’t contain the lungs: the abdominopelvic cavity houses abdominal and pelvic organs, the cranial cavity holds the brain, and the pericardial cavity contains the heart.
