MICROANATOMY

Detailed explanation-1: -Simple squamous epitheliumare found in alveoli and capillaries of lungs where gas exchange occurs.

Detailed explanation-2: -Simple squamous epithelium lines the air sacs, or alveoli, of the lungs. The cells of simple squamous epithelium provide a thin surface that facilitates easy passage of small molecules across the epithelium. The alveoli are the sites where gases are exchanged in the lungs.

Detailed explanation-3: -Simple squamous epithelia are found lining the cavities of the body including the pericardial, pleural, and peritoneal cavities, or in areas where passive diffusion occurs, such as glomeruli in the kidney and alveoli in the respiratory tract.

Detailed explanation-4: -Moving further down the lung, the alveoli are covered by types 1 and 2 epithelial cells [1]. The flat type I epithelial cells cover 95% of the peripheral lung surface.
