There are three kinds of blood vessels: arteries, veins, and capillaries. Each of these plays a very specific role in the circulation process. Arteries carry oxygenated blood away from the heart. They're tough on the outside but they contain a smooth interior layer of epithelial cells that allows blood to flow easily.
Answer: The squamous epithelial layer of tissues forms an important layer that lines the organs in the human or animal body.
Explanation:
The squamous epithelium ensures the absorption or transport of the materials, diffusion, filtration, and osmosis. It forms the part of the walls of the capillaries and that of alveoli of the lungs. If the squamous epithelium fails to function then capillaries may disintegrate, lung alveoli may rupture, and chances of organ failure will increase.
