Question

Quizplus · Accepted Answer

Type II alveolar cells are responsible for producing surfactant, but they do not contribute to the formation of the respiratory membrane. The respiratory membrane is composed of the capillary endothelial cells and the basal lamina of the type I alveolar cells. Type I alveolar cells form the majority of the respiratory membrane and provide a thin barrier for gas exchange.
