Question

The human lungs are covered by ……………. membrane.

Answer 1

Hint: Human lungs are enclosed by a serous membrane that forms a fluid-filled cavity where it can operate with ease. The membrane forms two pleura that adhere to each other.

Complete answer:
The pleural membrane is the name for the covering of lungs in humans. The two of these membranes consist of the space known as the pleural cavity where the lungs are situated. The two pleura are visceral pleura and parietal pleura. The parietal one stays attached to the chest wall whereas the visceral pleura which is the inner one covers the lungs and its adjoining structures.
The two pleura- visceral and parietal consists of the pleural space where the human lung is enclosed. A pleura is a serous membrane which forms a two-layered pleural sac by folding back onto itself. Therefore, the pleural space can be considered a potential cavity because the two pleura are attached to each other.
Their main function is to help the lungs in breathing. The cavity acts as a lubricant that allows the pleura to slide effortlessly against each other. This allows greater inflation of the alveoli during breathing.

So, the correct answer is "Pleural membrane".

Note:
The peritoneum is the membrane of the abdominal cavity or coelom in some vertebrates like annelids. The pericardium is a double-walled sac that encloses and protects the heart and roots of great vessels. The Glisson capsule is a capsule in the liver that covers it and the bases of the hepatic duct, hepatic artery, and portal veins.
