Pleura is the general name given to the mesothelium that lines the chest cavity.  Mesothelium surrounds the lungs and other organs.  The mesothelium layer that surrounds the lungs is called the visceral pleura.  The mesothelium layer inside the chest wall is called the parietal pleura.  And the space found between these layers is called the pleural space.
