The phosphate buffer system is important for the regulation of pH by the:
A)respiratory system
B)kidneys
C)brain
D)skeletal muscles

Question

Quizplus · Accepted Answer

The phosphate buffer system consists of dihydrogen phosphate ion (H2PO4-) and hydrogen phosphate ion (HPO42-), which act as a chemical buffer to regulate pH in the body. The kidneys play a major role in regulating pH by excreting or reabsorbing these ions as needed to maintain a stable pH balance. Therefore, the correct answer is B.
