Detailed explanation-1: -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-2: -The epithelium of the proximal convoluted tubule (PCT) of the nephron in the kidney has microvilli. Squamous epithelial tissue is made up of a single thin layer of flattened cells with irregular boundaries. They are found in the walls of blood vessels and air sacs of the lungs.
