Why do we need Blood? You might have heard that blood flows inside of something called blood vessels in your body. These are small tubes in your body. These are small tubes in your body. You might even be able to see some of them from the outside. All of these blood vessels in your body connect to the heart. One set of vessels, the arteries, carries blood away from the heart out toward all the different parts of your body. Down to your feet, up to your head, out to your hands to all of your muscles, then another set of vessels.
