The walls of the alveoli are composed of two types of cells. name these two types of cell

Two types are pneumocytes known as type I and type II cells found in the alveolar wall, and a large phagocytic cell known as an alveolar macrophage that moves about in the lumens of the alveoli, and in the connective tissue between them. Type I cells are squamous, thin and flat and form the structure of the alveoli.

Explanation: Look it up and you will find your answer :)

The two types are pneumocytes known as type one and type two cells found in the alveolar wall. Type one cells are squamous, thin and flat that form the structure of the alveoli.
