Question

Why are the physiological buffer systems more powerful in affecting pH?

Answer 1

Especially, renal physiology has several powerful mechanisms to maintain pH by the excretion of excess acid or base. That means, it is the kidneys play major role in removing excess acid or base. The lungs also play vital role in maintaining pH of the blood. The lungs remove excess CO₂ from the blood, a component of the principal pH buffer in the blood.
