The arrangement of epithelial cells in the skin is referred to as stratified squamous epithelium.

Epithelial cells in the skin are arranged in many layers to prevent wear and tear.

Simple squamous epithelial cells are extremely thin, flat, and form a delicate lining.

Simple squamous epithelium lines blood vessels, lung alveoli, the oesophagus, the mouth lining, and the skin.

Simple squamous epithelium facilitates transportation of substances through selectively permeable surfaces.
