The alveolar epithelium comprises two main cell types: the alveolar type I and alveolar type II cell.The type I cell is a complex branched cell with multiple cytoplasmic plates that are greatly attenuated and relatively devoid of organelles; these plates represent the gas exchange surface in the alveolus.On the other hand, the type II cell acts as the caretaker of the alveolar compartment.he type I cell is a complex branched cell with multiple cytoplasmic plates that are greatly attenuated and relatively devoid of organelles; these plates represent the gas exchange surface in the alveolus.

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.
