transport of oxygen

• what is the name of the molecule when oxygen binds with haemoglobin


  oxyhaemoglobin
• what is oxygen concentration measured in


  partial pressure (kpa)
• what happens when the partial pressure is high in the lungs


  the haemoglobin will have a high affinity to oxygen and so the oxygen will associate in the haemoglobin in the blood
• what happens when the partial pressure is low in the respiring tissues


  the haemoglobin will have a low affinity to oxygen and so the oxygen will dissociate from the oxyhaemoglobin to haemoglobin
• what happens when carbon dioxide levels increase in the blood


  the acidity increases (add more info)
• what happens as oxygen affinity decreases


  the partial pressure decreases
• what when the oxygen partial pressure is low


  it will be difficult for haemoglobin to load oxygen in respiring tissues
