GENERAL HISTOLOGY

Detailed explanation-1: -The endothelium is the epithelial tissue that lines vessels of the lymphatic and cardiovascular system, and it is made up of a single layer of squamous cells. Simple squamous epithelium, because of the thinness of the cell, is present where rapid passage of chemical compounds is observed.

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 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: -Simple squamous epithelial cells function as mediators of filtration and diffusion. Due to their simple and thin construct, they allow for easy transmembrane movement (i.e. across the membrane, and through the cell) of small molecules.

Detailed explanation-5: -Simple Squamous epithelial cells are located in the lungs and are a part of the circulatory system due to the lining they provide for the capillaries. Simple passive diffusion is enabled by their presence in the alveolar epithelium. The mouth, skin, and vaginal mucosa are lined by stratified squamous epithelial cells.
