Does Pleura Protect Lungs from Pathogens?

The pleurae

also serve as a division between other organs in the body, preventing them from interfering with lung function and vice versa. Because the pleura is self-contained, it can help prevent the spread of infection to and from the lungs.

Does the pleura protect the lungs?

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.

What does the pleura do in the lungs?

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. Normally, the pleura produces a small amount of fluid which serves as a lubricant to the lungs as they move back and forth against the chest wall during respiration.
