MICROANATOMY

Detailed explanation-1: -The pleura is a double layer of membranes that surrounds the lungs. Inside the space is a small amount of fluid. The fluid prevents the pleura from rubbing together when you breathe. Excess fluid in the pleural space is called pleural effusion.

Detailed explanation-2: -The thin space between the two pleural layers is known as the pleural cavity and normally contains a small amount of pleural fluid.

Detailed explanation-3: -Pleural fluid is a liquid that is located between the layers of the pleura. The pleura is a two-layer membrane that covers the lungs and lines the chest cavity. Pleural fluid keeps the pleura moist and reduces friction between the membranes when you breathe.

Detailed explanation-4: -The outer layer (parietal pleura) lines the inside of the chest wall. The very thin space between the layers is called the pleural space. A liquid, called pleural fluid, is in the pleural space.

Detailed explanation-5: -Pleural fluid is produced by the body in small amounts to lubricate the pleura, the thin layers of tissue that line the chest cavity and surround the lungs. This fluid lubricates the chest cavity and facilitates breathing.
