parietal pleura is known as
The parietal pleura is a membrane that lines the cavity in the chest that contains the lungs. Another membrane, called the visceral pleura, closely covers the lung surfaces. The narrow gap between the parietal and the visceral pleura is known as the pleural cavity or space.Within this space, pleural fluid forms a thin layer on the pleural membranes, preventing friction between the surfaces.arietal pleura refers to a membrane that lines the chest cavity that contains the lungs. Traumatic injuries, such as a stab wound, may cause air in the pleural space, leading to an open pneumothorax. Pneumonia may cause the pleural space to become inflamed, which may lead to a condition known as pleurisy.
