The human heart pumps blood through the body. The heart contracts, increasing the pressure in its valves. This increased pressure causes the blood to flow through the body. There are two types of blood vessels in the body. Arteries are the vessels that carry blood away from the heart, and veins are the vessels that bring the blood back to the heart.

Arteries and veins have different internal structures. The artery is smooth while the vein has valves. What is the advantage of having valves in the veins?

• The vein is carrying blood against gravity.

• Unoxygenated blood is heavier.

• The valves are needed to control carbon dioxide.

• The veins need to slow down the rate of blood flow.
