Keeping Your Circulatory System Healthy
By Brandi Waters |

1 It is important to keep your circulatory system working at its best. Your heart pumps blood to every part of your body. It travels through thousands of miles of blood vessels! Blood carries oxygen from your lungs. If there is a problem with your blood, your heart, or your blood vessels, your whole body can suffer. If you don't get enough oxygen to your brain, you might not be able to think clearly. If your stomach isn't getting enough oxygen, it might be hard for you to digest your food. If there is a problem with one of your blood vessels, blood could stop flowing to a part of your body. Without it, those cells could die.
