Diagram of Veins and Arteries?

Answer

The veins and arteries in the human body are essential for transporting blood. The arteries are elastic tubes that carry blood away from the heart while the veins are small tubes that carry blood to the heart. Veins are what are necessary when someone has a blood draw performed and a vein that is prominent in the arm is what is coveted by lab workers, nurses, or doctors. Veins have thinner walls than arteries, but are still functional because there is less pressure when blood is returned to the heart than when it is carried away. Diagrams of veins and arteries can be found online at sites like Leaving Bio.
