How does your blood maintain its pH

The pH of human blood must be kept within the narrow range of 7.1 to 7.7. Outside this range, proteins in the body lose their structure and ability to function. Fortunately, a number of buffers maintain the necessary acid/base balance. The carbonic acid/hydrogen carbonate buffer is the most important. 

As acids and bases are dumped into the bloodstream as a result of normal activity, the blood s buffer systems shift to effectively maintain a healthy pH. 

Depending upon the body s metabolic rate and other factors, the H2C03/HC03 equilibrium will shift according to Le Chatelier s principle. In addition, the lungs can alter the rate at which CO2 is 

Calculate the molarity of H+ in blood at a normal pH =i= 7.4 and at pH = 7.1, the lower limit of a healthy pH range. If the blood s pH changes from 7.4 to 7.1, how many times greater is the concentration of hydrogen ion  

The ratio of HC03 to CO2 is 20 1. Why is this imbalance favorable for maintaining a healthy pH
