NUTRITION: CIRCULATORY SYSTEM

The circulatory system trasnports oxygen and nutrients through our bodies. 

The CIRCULATORY SYSTEM has two parts:

- HEART: it  pumps the blood round the body through different blood vessels.

- BLOOD VESSELS (veins and arteries): they are thin tubes that carry the blood to all parts of the body.
