„The pleural membrane is a double-layered serous membrane that encloses and protects the lungs. The outer layer is attached to the wall of the thoracic cavity and diaphragm and is called parietal pleura. The inner layer, the visceral pleura, is attached to the lungs. Between the visceral and parietal pleurae is a narrow space, the pleural cavity, which contains a lubricating fluid secreted by the membranes.“

Ef rifbeinið stingst í lungað á þér og gat kemur á himnurnar umhversu lungað þá færðu eftirfarandi:
„Pneumothorax (collapsed lung): air enters the pleural cavity, either from the outside or from the lungs. This can be the result of a penetrating chest wound, or of an internal injury. A tension pneumothorax is where the punctured chest wall forms a one way valve so that air may enter (through the puncture) on inspiration, but cannot exit on expiration. With each breath air builds up in the chest cavity, compressing the lung still further, thus reducing the surface area available for gas exchange. It is a medical emergency.“
