  - - - Oxygen is transported in the blood with haemoglobin (oxyhaemoglobin) or in blood plasma (5%)
      - Each molecule of haemoglobin in our red blood cells can carry 4 molecules of oxygen
      - When the maximal amount of oxygen is bound to a molecule of haemoglobin this is called haemoglobin saturation
      - Haemoglobin usually 98% saturated with oxygen.
      - Carbon dioxide released from cells is carried in the blood in 3 forms
        
        plasma
        
        bicarbonate ions (60-70%)
        
        bound to haemoglobin
