Pleural Space

Mediastinoscopy pleural effusion thoracic surgery.
Pleural space. The pleural cavity is the space that lies between the pleura the two thin membranes that line and surround the lungs. The pleural space is normally filled with a small amount of fluid. The pleural space is a potential space that contains 2 to 10 ml of pleural fluid between visceral and parietal pleural layers that essentially represents interstitial fluid from the parietal pleura an ultrafiltrate of plasma. A pleura is a serous membrane which folds back onto itself to form a two layered membranous pleural sac.
The space between the pleural membranes that surround the lungs and the chest cavity. The pleural cavity also known as the pleural space is the thin fluid filled space between the two pulmonary pleurae known as visceral and parietal of each lung. When increased fluid occupies this space it is referred to as a pleural effusion and can severely restrict breathing depending on the size. The pleural cavity contains a small amount of liquid known as pleural fluid which provides lubrication as the lungs expand and contract during respiration.
