In ARDS, alveoli and respiratory bronchioles fill with fluid as a result of the:
A)compression on the pores of Kohn, thus preventing collateral ventilation.
B)increased capillary permeability, which causes alveoli and respiratory bronchioles to fill with fluid.
C)inactivation of surfactant and the impairment of type II alveolar cells.
D)increased capillary hydrostatic pressure that forces fluid into the alveoli and respiratory bronchioles.

Question

Quizplus · Accepted Answer

Lung inflammation and injury damages the alveolar epithelium and the vascular endothelium. Surfactant is inactivated, and its production by type II alveolar cells is impaired as alveoli and respiratory bronchioles fill with fluid or collapse.
