Question: 1 / 400

What is the term for the membrane that covers the lungs?

Pleura

The membrane that covers the lungs is called the pleura. This serous membrane consists of two layers: the visceral pleura, which directly covers the lungs, and the parietal pleura, which lines the chest wall. The pleura is essential for facilitating smooth movement of the lungs during respiration and plays a critical role in reducing friction between the lungs and the thoracic cavity.

In contrast, the pericardium is the membrane that surrounds the heart, the peritoneum is a serous membrane that lines the abdominal cavity and covers abdominal organs, while viscera generally refers to the internal organs housed within the body cavities, particularly in the abdomen. Each of these terms refers to different anatomical structures, highlighting why the pleura is the correct choice for the membrane covering the lungs.
