This is also where the trachea turns into the bronchi. pleura membranes that cover the surface of the lung and the cavity surrounding the lungs parietal pleura covers the surfaces surrounding the lungs: the rib cage, diaphragm, and mediastinum. visceral pleura directly covers the lungs pleural space/cavity The space that is formed between the pleurae. Normally, this space is empty except for a scant amount of fluid. However, in the diseased state, this cavity can fill with air or fluids. anatomical organization of the respiratory system allows the respiratory system to perform three main functions: 1) air conduction, 2) air filtration, and 3) exchange of gases - aka respiration Conducting portion of respiratory system
