Which of the following systems helps to maintain the pH of blood?

The buffer system which helps to maintain the pH of blood between 7.26 to 7.42 is

Human blood has a narrow Ph range of 7.3-7.4 , which must be maintained for methabolic processes to function properly. To keep the Ph in this range requires a delicate balance between the concentration of the conjugate acid-base pairs making upto the buffer system. The main buffer is a carbonic acid/ hydrogencarbonate system, which involves the following three equilibria. CO_(2)(g)hArrCO_(2)(aq) CO_(2)(aq)+H_(2)O(l)hArrH_(2)CO_(3)(aq) H_(2)CO(aq)+H_(2)O(l)hArrHCO_(3)^(-)(aq)+H_(3)O^(+)(aq) Carbonic acid (H_(2)CO_(3)) is a weak acid and HCO_(3)^(-) (aq) is its conjugate base. At the temperature of the human body, the pK_(a) for carbonic acid is 6.4 However, the normal concentration of CO_(2)(g) in the lungs maintanis a ratio of HCO_(3)^(-)(aq)//H_(2)CO_(3)(aq) in blood plasma of about 8:1 . The carbonic acid concentration in the bloos is largely controlled by breathing and respiration. Hydrogencarbonate ion concentration is largely controlled by excreation in urine. If blood pH rises above 7.4 , a potentially life-threatening conditon called alkalosis can result. This can happen in patients who are hyperventilating from severse anxiety, or in climbers suffereing from oxygen deficency at high altitude. (Given: log 2=0.3) Calculate the maximum permissible value of ([H_(2)CO_(3)])/([HCO_(3)^(-)]) in the human blood to just prevent alkalosis.
