Final answer:

The buffer mechanism in the blood is the fastest response to maintain pH when it becomes acidic, followed by the respiratory and renal mechanisms.


Explanation:

Buffer mechanism in the blood is the fastest and most immediate response when blood pH becomes more acidic. This system involves chemical buffers that make adjustments to pH within seconds, helping to maintain pH within a narrow range.

Respiratory mechanisms can also adjust blood pH quickly by exhaling CO2 to increase pH. However, the renal system can also adjust blood pH by excreting hydrogen ions and conserving bicarbonate, although this process is slower, taking hours to days to have a noticeable effect.
