The parietal pleura is the lining of the thoracic cavity. It forms the outer layer of the pleural sac, lining the interior surface of the chest wall and the diaphragm and extending to cover mediastinal structures as part of that lining. The visceral pleura, in contrast, directly covers the lungs. The space between these two layers contains pleural fluid to reduce friction during breathing. Therefore, the description that best fits the parietal pleura is the one that states it lines the interior surface of the chest wall and diaphragm.
