function of alveolar macrophagesThe function of alveolar macrophage in the lungs is to remove dust particles and other debris from alveolar spaces.-Sheshi Aveolar macrophages work to break up surfactanct in the aveoli which exists to decrease surface tension in the lungs. If there is a disorder where the macrophage does not function correctly, such as in PAP, the surfactant will not be broken up and decreased ventilation will occur resulting in less oxygen delivery.
Gas Exchange Between Alveolar Spaces and Capillaries. The function of the respiratory system is to exchange two gases: oxygen and carbon dioxide. The exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
