The pH-regulating mechanism that has the least capacity to buffer an ongoing pH imbalance is the:
A)buffer systems
B)respiratory mechanism
C)cerebral mechanism
D)renal mechanism

Question

Quizplus · Accepted Answer

Buffer systems have the least capacity to buffer an ongoing pH imbalance because they act immediately but can only neutralize small amounts of acids or bases, making them less effective for correcting significant or ongoing imbalances compared to the respiratory and renal mechanisms, which can handle larger disturbances over longer periods. There is no cerebral mechanism specifically dedicated to pH regulation; the brain influences respiration but does not directly buffer pH.
