GENERAL HISTOLOGY

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: -Simple squamous epithelium also makes up the alveoli in the lungs (Figure 3), where rapid gas exchange occurs, as oxygen enters the bloodstream through alveolar blood vessels and carbon dioxide exits as waste.

Detailed explanation-3: -Squamous, or flattened, epithelial cells, very thin and irregular in outline, occur as the covering epithelium of the alveoli of the lung and of the glomeruli and capsule of the kidney.

Detailed explanation-4: -Simple squamous epithelium lining the alveoli in the lungs allows the gas exchange between the alveoli and the blood vessels while also forming a barrier between the outside and the internal body fluids.

Detailed explanation-5: -Simple squamous Areas where it can be found include: skin, capillary walls, glomeruli, pericardial lining, pleural lining, peritoneal cavity lining, and alveolar lining.
