- Majority of oxygen is carried by haemoglobin
- Oxygen saturated haemoglobin is known as oxy haemoglobin
- At the tissues, the acidity of the blood increases (co2 and lactic acid) resulting in a lower partial pressure.
- This causes oxygen to disassociate from the haemoglobin and released onto the myoglobin in the tissue.
- This is known as the bohr effect
- During exercise, increased co2 causes more disassociation of oxygen due to a lower pH level in the working muscles.
