The pleura of the thorax are the serous membranes which enclose the upper chest cavity. The pleura enclose the lungs and protect them from friction against the wall of the thorax. It is formed of two layers - the visceral and parietal pleura - between which is lubricated by serous fluid. The parietal pleura is the exterior layer of this pulmonary pleural sac, which connects to the thorax wall, the mediastinal membrane, and the diaphragm muscle. Research Parietal Pleura
