Arteries carry oxygen-rich blood away from the heart to the rest of the body. They have thick walls made of three layers of tissue: the tunica intima, tunica media, and tunica adventitia. The thick walls of arteries allow them to withstand the high pressure of blood that is pumped by the heart.
Explanation:
Veins carry deoxygenated blood back to the heart. They have thinner walls than arteries and do not need to withstand as much pressure. Veins have valves that help to keep blood flowing in one direction, towards the heart.
Arteries carry blood away from the heart, and veins carry blood towards the heart. With the exception of pulmonary blood vessels, arteries carry oxygenated blood and veins carry deoxygenated blood. Arteries have thick walls with muscle tissue. Veins have thinner walls and use valves to keep your blood flowing.
