CO2 + H2O gives H2CO3 by carbonic anhydrase later H2CO3 disociates into H+ and HCO3- .
CO2 is regulated by lungs and H + is regulated by kidney.
Control for acid base balance in lungs is regulation of CO2 expired air.
Kidnes regulate the acid - base balance in our body by excreting hydrogen ions and generating bicarbonate ions this maintaining the blood pH.
