Where does haemoglobin have a lower oxygen affinity?
At respiring tissues (more CO2)

What is the Bohr effect?
This is where higher PCO2 causes a lower oxgyen affinity, caused by respiring cells. This allows more oxygen to be released into the cells during activity.

Does Foetal haemoglobin have a higher or lower O2 affinity than Maternal haemoglobin?
Higher - this is because the only way to absorb oxygen is through the mother, so it must be strong at absorbing

Put the types of haemoglobin in order of affinity (lowest first):
Bohr -> Normal -> Foetal -> Myoglobin
