Pleural Pressure
atmospheric pressure
The lubricating fluid secreted by the pleura is located between the two layers of the pleural membrane: the visceral and parietal pleura. This fluid helps reduce friction between the two layers during breathing movements.
They are called pleura. There are 2 layers, the visceral (nect to the lung) and the parietal (on the outside), with a cavity in between them called the pleural cavity which contains a small amount of fluid. they are thin layers of smooth epithelium. The two layers rub against each other during breathing, the fluid helps to prevent friction.
Lungs are totally elastic organs. They are kept in position by negative pressure in visceral and parietal pleura. There is no gas in cavity between both pleura. In fact both pleura are part of one one collapsed balloon. Very small amount of fluid in cavity between pleura keeps it lubricating. If air accidentally enters there, then there is a condition called as Pneumothorax. There is also a condition called as Tension Pneumothorax. Which is an emergency.
That is a good question! You have a pleura, that surround the lungs. You have inner and outer layers (visceral and parietal layers). Both are connected to each other. In fact you have a balloon, in which your lungs grow. You take out the air from the balloon and you get the pleura. So both the come together at the blood vessels and bronchi. The lungs are totally elastic organs and collapse to small ball, if air enters the pleura. This elasticity of lungs create the negative pressure in the pleura. The negative pressure in pleura keeps the lungs in expanded condition. You have little fluid in the pleura. This reduces the friction between the outer and inner layers of pleura.

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 pleural space is located between the two layers of the pleura, which are thin membranes that surround the lungs. The visceral pleura is the inner layer that covers the lung, and the parietal pleura is the outer layer that lines the chest cavity. The pleural space contains a small amount of fluid that helps reduce friction during breathing.
The answer is a vacuum. It is called the intrapleural space and is the negative pressure inside the thoracic cavity between the visceral pleura and the parietal pleura. When a person looses this pressure due to an injury and air comes into this space, they are said to have a collapsed lung.
The membrane between the lungs and the muscles of the chest cavity is called the pleura. You have probably heard of the disease 'pleurisy'. When the pleural area gets sick or inflamed it is called pleurisy. Cancer can be formed there too. It is an important part of the lungs because it keeps it moisturized and able to move up and down.
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.
The space between the breasts is called the cleavage.
The outer membrane that covers the lungs is called the pleura. It consists of two layers - the visceral pleura, which is directly attached to the lungs, and the parietal pleura, which lines the chest cavity. The pleura helps to protect and support the lungs while allowing them to move smoothly during breathing.
