An aqueous solution in the blood that helps to regulate pH is called buffer solution.
Explanation:
Buffer solution is a specific type of solution which able to resist the pH change when small amount of acid or base is added to it.There are various buffer system present inside our body that helps to regulate the pH of our body.
The clinical contidition in which the blood pH is above is 7.45 is called alkalosis it can be overcome by addition of required amount of acid or H+ ion to neutralize to excess base.
For example during alkalosis the CO2 that is produced during cellular respiration reacts with water to generate carbonic acid(H2CO3) which will help to neutralize the excess base to maintain the normal pH of the blood.
