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. Theyâre tough on the outside but they contain a smooth interior layer of epithelial cells that allows blood to flow easily.
Capillaries are tiny blood vessels connecting the small arteries (arterioles) to the small veins (venules). The blood vessels carry oxygen and nutrients to all the individual cells in the body.rteries carry blood to the tissues, and veins carry blood back to the heart. In betweenare tiny blood vessels so small that red blood cells can pass through single file, allo â¦ wingthe oxygen to diffuse into the surrounding tissue. These are called capillaries.
