WebbSimple Squamous Epithelia. A single layer of thin, flattened epithelial cells lines the interior of blood vessels. They provide a slick surface that promotes a smooth flow of blood cells through the vessel. These lining cells can be surrounded by smooth muscle cells, which form a thick, contractile wall for a blood vessel.
