Which pleural layer lines the inside of the chest cavity?

Explanation:
Parietal pleura lines the inside of the chest cavity, including the thoracic wall, the diaphragm, and the mediastinum. The layer that covers the lungs themselves is the visceral pleura, and the space between these two layers is the pleural cavity, which contains a small amount of fluid to reduce friction during breathing. The alveolar membrane is part of the air–blood barrier in the lungs, not a lining of the chest wall. So, the lining inside the chest cavity is the parietal pleura.
