'There are two type of blood vessels:arteries which carry blood away from the heart; and veins, which transport blood toward the heart. Arteries are thicker and stronger than veins, and their muscular walls help propel blood. Unlike arteries, veins contain valves to prevent the blood from flowing backward.'
