Explanation:
Detailed explanation-1: -Carbonic acid then dissociates into bicarbonate and a hydrogen ion. This reaction is one of the many buffer systems in the human body; it resists dramatic changes in pH to allow a person to remain within the narrow physiological pH range.
Detailed explanation-2: -The kidneys regulate the pH of the blood by excreting acids in urine. They also produce and regulate bicarbonate, which increases blood pH.
Detailed explanation-3: -The pH of blood is maintained at 7.4 by the carbonic acid – bicarbonate ion buffering system.
