A space between the inner and outer pleura of the chest.
Cavity in the thorax that contains the lungs.
The space between the visceral and parietal ‘pleura, which is normally very small as the pleural membranes are in close contact. The introduction of fluid (pleural effusion) or gas separates the pleural surfaces and increases the volume of the pleural space.
The normally restricted space between the parietal and the visceral pleura, which slide over one another as the individual breathes in and out. If gas or fluid is introduced as a result of injury or infection, the pleural surfaces are separated and the pleural space increases in volume. This usually causes breathing difficulties.
The potential space between the parietal pleura that lines the thoracic cavity and the visceral pleura that covers the lungs. It contains serous fluid that prevents friction.
The region encompassing the lining of the chest cavity, the space accommodating the lungs, and the membrane that envelops the lungs collectively constitutes the thoracic cavity.
The space between the two layers of the pleura, a membrane that lines the chest wall and covers the outer surface of the lungs.
The hypothetical gap between the membrane that surrounds the lungs and the one that lines the interior of the chest.
