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: This type of epithelium typically lines blood vessels and body cavities and regulates the passage of substances into the underlying tissue. Simple cuboidal epithelium: This type of epithelium is typically found in glandular (secreting) tissue and kidney tubules.

Detailed explanation-3: -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.
