A
A measure of concentration of that gas in a mixture of gases
2
Q
Where will haemoglobin have a higher affinity for oxygen?
A
Oxygen-rich areas (e.g lungs) where there is a high pO2, promoting oxygen loading
3

A
Oxygen-starved areas (e.g respiring tissues) where there is a low pO2, promoting oxygen unloading.
