*The PlLeural Cavity is filled with a small amount of fluid which forms a thin film of liquid between the pleural layers. This is vital in that in prevents separation of the two pleural layers and lubricates the surface, so the lungs can move easily within the thoracic cavity.
*The Pleural Cavity is filled with a small amount of fluid which forms a thin film of liquid between the pleural layers. This is vital in that in prevents separation of the two pleural layers and lubricates the surface, so the lungs can move easily within the thoracic cavity.
*The Pleural Fluid also provides the surface tension keeping the lung suitably close to the wall of the thorax.
*The pleural sacs are separate so that in the event of one being punctured, the other lung can continue to function effectively.
