How does the body respond if respiratory mechanisms are unable to stop a pH shift?
A) A renal physiological buffer system involving the excretion of either an acid or alkaline urine will be initiated within 24 hours.
B) Bicarbonate buffers immediately combine with any added acid or alkali that enters the body fluids, thus preventing drastic changes in pH.
C) Phosphate buffers immediately combine with any added acid or alkali that enters the body fluids, thus preventing drastic changes in pH.
D) Protein buffers immediately combine with any added acid or alkali that enters the body fluids, thus preventing drastic changes in pH.

If respiratory mechanisms are unable to stop a pH shift, the kidneys will initiate a renal physiological buffer system within 24 hours to excrete either an acid or alkaline urine to regulate pH. Bicarbonate, phosphate, and protein buffers are all part of the body's buffer systems, but they can only provide temporary support and cannot completely compensate for a sustained pH imbalance.
