    Head Area: The nose and mouth take in oxygen that goes through the throat and into the lungs. There are 2 ways, but a little flap opens when oxygen comes in and closes right after. This is used so food doesn't get in the wrong way.

    Chest Area: Capillaries in the lungs move the oxygen to the heart to pump it throughout the body.
