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.
There are three different types of blood vessels: arteries (which carry blood away from the heart) veins (which carry blood toward the heart) and capillaries (which carry blood from arteries to veins).So veins are a type of vessel, but not the only type.eins have valves which make them unique, (as compared to arteries or capillaries). This is to prevent blood from going in the opposite direction. Since arteries lead away fr â¦ om the heart, the blood travels through using the pressure differential.
