What is the name of the membrane surrounding the lungs?

Pleura
Pericardium
Endocardium
Peritoneum

The correct answer is: Pleura

The membrane surrounding the lungs is called the pleura. This double-layered structure consists of two main parts: the visceral pleura, which directly covers the lung tissue, and the parietal pleura, which lines the chest wall and diaphragm. The pleura plays a crucial role in the respiratory system by allowing smooth movement of the lungs during inhalation and exhalation, reducing friction between the lungs and the thoracic cavity. It also helps to create a vacuum that aids in lung expansion. In contrast, the pericardium is the membrane that surrounds the heart, while the endocardium is the inner lining of the heart chambers. The peritoneum is a serous membrane that lines the abdominal cavity and covers the abdominal organs. Each of these membranes has a specific location and function in the body, which is why understanding the role of the pleura is essential for anyone studying respiratory physiology and emergency medical response.
