BRAINCAKELoading and Unloading Oxygen
The role of haemoglobin is to transport oxygen.
In human lungs haemoglobin binds or associates with oxygen readily when there is a high partial pressure of oxygen in the environment.
The loading of haemoglobin with oxygen in the lungs is due to its high affinity for oxygen at high partial pressures of oxygen.
