System.
The circulatory system is
made up of blood vessels that carry blood away from and towards the heart.
Arteries carry blood away from the heart and veins carry blood back to the
heart. The circulatory system carries oxygen, nutrients, and
hormones to cells, and removes waste products, like carbon dioxide.
