Question

Quizplus · Accepted Answer

Type II cells, also called pneumocytes, produce and secrete pulmonary surfactant, which helps reduce surface tension in the alveoli and prevents their collapse. Type I cells make up the majority of the alveolar surface and are involved in gas exchange. Alveolar macrophages are immune cells that remove debris and pathogens from the lungs. Chondrocytes are cartilage cells and are not involved in lung function.
