Simple squamous epithelial tissue can be found in the air sacs (or alveoli) of the lungs as well as in the tiniest blood vessels called capillaries. Why is it important to have a single, thin layer of tissue in these locations, as opposed to having a thick layer of tissue? The tissue layer is thin so that molecules of oxygen and carbon dioxide gas can diffuse easily across. The tissue layer is thin to facilitate secretion of hormones. The tissue layer is thin so that nutrients can be absorbed more easily.

Identify each of the following epithelial tissues from their functional description: Epithelium can function in diffusion, filtration, secretion, and protection based on location. Pseudostratified columnar epithelium can function in absorption, secretion, and protection. Simple squamous epithelium functions in the protection of underlying layers. Transitional epithelium functions in the movement of a secretion (like mucus) across the apical surface of the tissue. Stratified squamous epithelium accommodates distension and relaxation with changes in organ volume. Simple cuboidal epithelium.
