Definition
The visceral pleura is the inner layer of the pleural membrane, which directly covers the surface of the lung. It's like a thin, clingy film that hugs the lung tightly. This layer contains blood vessels, nerves, and lymphatic vessels that supply the lung. The visceral pleura is thinner and more delicate than the parietal pleura. It adheres closely to the lung tissue, following its contours. Its main function is to provide a protective covering to the lung and contribute to the pleural space. It ensures smooth movement of the lung during breathing.
