  Text H. The circulatory system
  Arteries
  Arteries are tough, elastic tubes that carry blood away from the heart. As the arteries move away from the heart, they divide into smaller vessels. The largest arteries are about as thick as a thumb. The smallest arteries are thinner than hair. These thinner arteries are called arterioles. Arteries carry bright red blood! The color comes from the oxygen that it carries.
  Veins
  Veins carry the blood to the heart. The smallest veins, also called venules, are very thin. They join larger veins that open into the heart. The veins carry dark red blood that doesn't have much oxygen. Veins have thin walls. They don't need to be as strong as the arteries because as blood is returned to the heart, it is under less pressure. The heart The heart is the strongest muscle. The heart is divided into two sides. The right side pumps blood to the lungs where it picks up oxygen. The left side pumps oxygen-soaked blood out to the body. They do not work on their own, but together as a team. The body's blood is circulated through the heart more than 1,000 times per day. Between five and six thousand quarts of blood are pumped each day. The heart is about the same size as your fist. Your heart's job is to pump blood around the body. Its muscles contract and squeeze out blood. The left-hand side pumps blood from the lungs to the rest of the body. The right-hand side pumps stale blood from the body back to the lungs for a fresh supply of oxygen.
