Quizplus · Accepted Answer

1) In a pneumothorax, air enters the pleural space, causing the lung on the affected side to collapse due to loss of negative pressure. 2) Normally, the visceral and parietal pleura are in close contact, but in pneumothorax, they separate because of the air in the pleural space. 4) The chest wall may move outward on the affected side due to the pressure from the air in the pleural space pushing against it.
