Oxygen Transport and Oxygen Dissociation Curve -

 
  • Blood is the medium of transport for O_{_{2}} and CO_{_{2}}. 
  • About 97 percent of O_{_{2}} is transported by RBCs in the blood. 
  • In the tissues, there is 
    • low pO_{_{2}}  
    • high pCO_{_{2}}  
    • high H+ concentration 
    • higher temperature  
  • These conditions are favourable for dissociation of oxygen from oxyhaemoglobin.
  • This clearly indicates that O_{_{2}} gets bound to haemoglobin in the lung surface and gets haemoglobin in the lung surface and gets dissociated at the tissues.
  • Every 100 ml of oxygenated blood can deliver around 5 ml of O_{_{2}} to the tissues under normal physiological conditions.

 

Hence the correct option is all of the above
