Circulation Of Blood

Our circulatory system carries materials to and from  every cell of your body via a series of blood vessels called arteries, capillaries and veins. the heart is the pump that keeps the blood moving and without it the cells would soon be starved of the materials they need to function.

Our 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.
