The Pleural Cavity And Pleurisy
In human anatomy, the lungs are surrounded by the pleural cavity. Basically this cavity is the space created between two layers of pleura. The pleura folds over itself to make this space which contains some pleural fluid. The outer layer is called the parietal pleura and the inner layer is referred to as the visceral pleura. Parietal pleurae are attached to the chest wall, or thoracic wall. Visceral pleurae cover the lungs as well as bronchi, blood vessels and nerves.
