What is the name of the membrane that covers the lungs?

The membrane that covers the lungs is called the pleura. This serous membrane consists of two layers: the visceral pleura, which directly adheres to the lung surface, and the parietal pleura, which lines the chest cavity. This dual-layer structure plays a critical role in facilitating lung expansion and contraction during breathing by reducing friction between the lungs and the chest wall.

In contrast, pleurisy refers to inflammation of the pleura, while the pericardium is the membrane surrounding the heart, and the peritoneum is the membrane that lines the abdominal cavity. Understanding the anatomical structures and their functions is essential for recognizing various conditions and potential complications in respiratory health.
