Circulatory system
Blood is pumped around your body through a network of blood vessels. Your heart and these blood vessels make up the circulatory system.
- Arteries carry the oxygen-rich blood from your heart to deliver it to your body. Coronary arteries are special arteries that supply the heart with blood to keep it working well.
- Capillaries are tiny blood vessels that connect arteries and veins. Capillaries carry blood to the body cells where oxygen and nutrients are delivered, and waste is taken away.
- Veins carry the blood from your body back to your heart after the oxygen and nutrients are delivered. By now the blood is low in oxygen and needs to pass through the lungs again and receive more oxygen.
