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.
The alveolar epithelium is composed of two main cell types. The type I cells are large flat thin cells that cover about 95% of the surface area. They are a major part of the epithelial barrier and express genes that indicate they have significant metabolic functions.he alveolar epithelium is composed of two main cell types.
