an optimal loading of haemoglobin with oxygen in the lungs and a high desaturation in the periphery are ensured by a highly cooperative oxygen binding of 4 subunits as well as by different effectors -- 2,3 dpg , chloride , ph , temperature ... -.a number of differently built-up haemoglobins will ensure a sufficient oxygen supply of individual ontogenetic stages of development in the human organism .
