- Arterio-venous oxygen difference (a-vO2)
- the difference in oxygen levels in the arteries before diffusion and in the veins after diffusion
- during exercise muscles extract large amounts of oxygen from the blood and so the a-vO2 diff is high
- this increase in a-vO2 diff affects gaseous exchange at the alveoli
