What surrounds the lungs?
A
Respiratory Membrane
B
Pleura
C
Sac
D
Mucous Membrane
Explanation: 

Detailed explanation-1: -A pleura is a serous membrane that folds back on itself to form a two-layered membranous pleural sac. The outer layer is called the parietal pleura and attaches to the chest wall. The inner layer is called the visceral pleura and covers the lungs, blood vessels, nerves, and bronchi.

Detailed explanation-2: -The pleura includes two thin layers of tissue that protect and cushion the lungs. The inner layer (visceral pleura) wraps around the lungs and is stuck so tightly to the lungs that it cannot be peeled off. The outer layer (parietal pleura) lines the inside of the chest wall.

Detailed explanation-3: -The chest cavity is lined by a thin shiny membrane called the pleura, which covers the inside surface of the rib cage and spreads over the lungs as well.

Detailed explanation-4: -The pleural cavity is bounded by a double layered serous membrane called pleura. Pleura is formed by an inner visceral pleura and an outer parietal layer. Between these two membranous layers is a small amount of serous fluid held within the pleural cavity.
