If the pleura does not secrete enough fluid friction can occur between the corresponding linings (visceral and peritoneum) causing damage to the organ
Gas exchange does not occur in the pleura. The pleura is a membrane that lines the outside of the lungs and inside of the chest cavity. Gas exchange, where oxygen is taken in and carbon dioxide is removed, happens in the alveoli of the lungs.
The innermost layer of the pleura is known as the visceral pleura. This thin membrane covers the surface of the lungs and is in close contact with the lung tissue.
Your lung is totally elastic organ. If air enters the pleura, lung will contract. It will be useless for respiration in such case. You have to put under water seal to take out the air from the pleura. If air happens to enter in both of the pleura, you will die in 5 minutes.
Visceral pleura. The parietal pleura surrounds the outside of the lung. When you are dissecting, the parietal pleura is the layer of lung that you remove. It is difficult to remove the visceral pleura, but not impossible.
The visceral pleura is deep to the parietal pleura. The visceral is closer to the lungs.
The double membrane that covers the lungs and lines the thoracic cavity is called the pleura. It consists of two layers: the visceral pleura attached to the lungs and the parietal pleura lining the thoracic cavity. The pleura produces a small amount of fluid that helps reduce friction during breathing.
The membrane lining on the lung is the visceral pleura and the membrane lining the inside of the chest cavity is the parietal pleura.
Pleural Cavity is the body cavity that surrounds the right and left lung. The pleura is a serous membrane which folds back to form a two-layered, membrane structure. The thin space between the two pleural layers is known as the pleural cavity; it normally contains a small amount of pleural fluid. The outer pleura parietal pleura is attached to the chest wall. The inner pleura, visceral pleura covers the lungs and adjoining structures.
Visceral pleura. The parietal pleura surrounds the outside of the lung. When you are dissecting, the parietal pleura is the layer of lung that you remove. It is difficult to remove the visceral pleura, but not impossible.
The difference between these two pleura is that the parietal pleura is the outtermost covering of the lung which is adhered to the inner thoracic wall, while the visceral pleura is the lining which is directly adhered to the lung itself. The space between these two pleuras is know as the pleual cavity.
The pleura are part of the respiratory system. The pleura are the membranous coverings of each lung.
A Pleura is the lung cover.
