AThe visceral pleura
BThe parietal pleura
CThe pleural cavity
DThe pulmonary plexus
Answer & Solution
Correct answer: B. The parietal pleura
1. The pleura has two layers separated by the pleural cavity.
2. The visceral pleura is superficial to the lungs and extends into the lung fissures.
3. The parietal pleura is the outer layer connecting to the thoracic wall, mediastinum and diaphragm.
4. So the second option is correct, and the pleural cavity is the space between the two rather than a layer.
