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.

1. a type of cell found in the periphery of the islets of Langerhans that secretes glucagon. 2. acidophil (2). alveolar cell pneumonocyte; any cell of the walls of the pulmonary alveoli; often restricted to the cells of the alveolar epithelium (squamous alveolar cells and great alveolar cells) and alveolar phagocytes. cell whose function is to reproduce the organism. Early in development, primordial germ cells are found in the genital ridges of the embryo. Later, in the testis, the primordial germ cells are called spermatogonia, and in the ovary, they are called oogonia.
