Detailed explanation-1: -The outer layer is called the parietal pleura and attaches to the chest wall. The inner layer is called the visceral pleura and covers the lungs, blood vessels, nerves, and bronchi. There is no anatomical connection between the right and left pleural cavities.
Detailed explanation-2: -The visceral pleura is continuous with the parietal pleura at the hilum of the lung. The parietal pleura is thicker than the visceral one, lines the pulmonary cavities and adheres to the thoracic wall, mediastinum and diaphragm.
Detailed explanation-3: -A pneumothorax is a collection of air outside the lung but within the pleural cavity. It occurs when air accumulates between the parietal and visceral pleura inside the chest. The air accumulation can apply pressure on the lung and make it collapse.
