Vein Types. Veins can be categorized into four main types: pulmonary, systemic, superficial, and deep veins. Pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart. Systemic veins return oxygen-depleted blood from the rest of the body to the right atrium of the heart. Superficial veins are located close to the surface of the skin and are not located near a corresponding artery.
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.
