- IS WHERE GAS EXCHANGE OCCURS;
- PICKS UP OXYGEN FROM INHALED AIR;
- EXPELS (gets rid of) CARBON DIOXIDE AND WATER;
- MOVES GASES INTO AND OUT OF THE BLOOD

From the heart to every cell in your body
Oxygen is then processing the nutrients and release energy
As the muscles the oxygen up, carbon dioxide is produced and absorbed into blood
-
Carry blood back to the heart
From the capillary to the heart
It carries carbon dioxide and is pumped back to the heart then on to the lungs
The lungs get rid of the carbon dioxide and breathe in more oxygen
