Ø    How does it work?

 The OXYGEN that comes from the LUNGS, MIXES UP with your BLOOD.

The HEART pumps the BLOOD with OXYGEN around the BODY.

Ø    How much blood have we got in our body?

We have got 5 litres of blood

Ø    A car needs petrol or gasoline to run

Ø    Our body needs oxygen to move

CIRCULATORY SYSTEM: function: CIRCULATION

• It transports: Nutrients, Oxygen and Water to all your body.
• It is formed by BLOOD, the HEART and BLOOD VESSELS (VEINS: Blood back, ARTERIES: Blood away)
