| Gas exchange (diffusion into or out of blood?) |
|
Definition
O2 is higher in the lungs than in the blood --> so it diffuses into the blood
CO2 is higher in the blood than in the lungs --> so it diffuses out of blood |

states that pressure and volume are inversely related - if pressure goes up, volume goes down.
High pressure = low volume = air goes out
Low pressure = high volume = air goes in |
