What does the blood do in your body?

The red blood cells take oxygen to the heart. But blood is very important for your body to function correctly. Your brain needs blood to work as well the kidneys to filter out wastes. The white blood cells help your immune system and get rid of bacteria when you are sick. The main job of blood is to give oxygen to the heart, though. Without blood, the body would not function at all.
