dissociation of oxyhaemoglobin in the body cells is favoured by low Po2 and high Pco2..explain in detail.,this is given n the topic tst

Oxygen dissociation curve explains us the transport of oxygen in the body.... There are some factors due to which oxygen is transported.... When the partial pressure of oxygen is more, the partial pressure of carbon dioxide is less, H+ concentration is less, tempreture is less... All these conditions are favourable to associate oxygen with haemoglobin and this all happens on the lung surface whereas when the partial pressure of oxygen is less , partial pressure of carbon dioxide is more, H+ concentration is more, tempreture is more... All these conditions are favourable for dissociation from haemoglobin and this all happens on the tissue surface.... On lung surface the partial pressure of oxygen is 104mm-Hg where as of carbon dioxide is 40mm-Hg.... On tissue surface the partial pressure of oxygen is 40 mm-Hg and of carbon dioxide is 45mm-Hg... Hope this helps...
