What happens in the Lungs

Getting there

Gas exchange

- Rylan is deoxygenated blood

-the co2 in the blood moves to the air

- o2 moves from the air into the blood in the capillaries

- now Rylan is oxygenated blood

- Rylan travels on the outside of the Bronchiole tubes

- at the ends are Alveoli (air sacs)

- surrounding the Alveoli are capillaries
