2. Gaseous exchange between the blood in the capillaries and the body cells.
4. Explains difference between high and low conc. The steeper this gradient (difference between concentration levels at high and low areas) the faster diffusion occurs.

1. The movement of oxygen from the air into the blood, and carbon dioxide from the blood into the air.
3. Volume of air that can be forcibly inspired after a normal breath. Decreases during exercise.
5. Volume of air breathed in or out per minute. Big increase during exercise.
6. The movement of gas molecules from an area of high concentration or partial pressure to an area to an area of low concentration or partial pressure.
7. Volume of air breathed in or out per breath. Increases during exercise.
8. Volume of air that remains in the lungs after maximum expiration. Remains the same during exercise.
16. Breathing in.
