Veins are elastic vessels that transport blood to the heart.
The smallest veins in the body are called venules. They receive blood from the arteries via the arterioles and capillaries . The venules branch into larger veins which eventually carry the blood to the largest veins in the body, the vena cava . The blood is then transported from the vena cava to the right atrium of the heart . Find great deals on quality laboratory equipment.
