Final answer:
The term that refers to the collapse of part or all of a lung is pneumothorax. It can be caused by various factors, including trauma, lung disease, or spontaneous rupture of a small air sac in the lung. Examples of conditions associated with lung collapse include pulmonary fibrosis and emphysema.
Step-by-step explanation:
The term that refers to the collapse of part or all of a lung is pneumothorax. Pneumothorax occurs when air leaks into the space between the lung and the chest wall, causing the lung to collapse. This can be caused by various factors, including trauma, lung disease, or spontaneous rupture of a small air sac in the lung. Treatment for pneumothorax may involve the use of a chest tube to remove the air and allow the lung to re-expand.
Examples of conditions associated with lung collapse include pulmonary fibrosis and emphysema. In pulmonary fibrosis, the lung tissue becomes stiff and less compliant, leading to decreased lung volume and increased risk of collapse. Emphysema, on the other hand, is a lung disease characterized by the destruction of alveoli, which can result in loss of lung elasticity and collapse.
