Arteries and veins are the two main kinds of blood vessels that carry your blood around the body.
But, they both do different jobs. Your arteries carry blood filled with oxygen, and your veins carry blood filled with carbon dioxide and other waste materials that the body gets rid of. When we breathe in, our lungs fill with up with oxygen that keeps us alive. Then, when we breathe out, the air that we let out contains carbon dioxide, which we get rid of.
Did you know?
It takes about a minute for blood to travel all the way from your heart to your toes and back again!
