MICROANATOMY

Detailed explanation-1: -Simple squamous epithelial cells are flat and thin enough to allow molecules to pass via diffusion. This cell type is found in the walls of capillaries, linings of the pericardium, and alveoli.

Detailed explanation-2: -Squamous cells are thin, flat cells that look like fish scales, and are found in the tissue that forms the surface of the skin, the lining of the hollow organs of the body, and the lining of the respiratory and digestive tracts.
