Question

Quizplus · Accepted Answer

The kidneys play a major role in regulating the pH of extracellular fluid through the excretion of hydrogen ions. When the blood becomes too acidic, the kidneys excrete more hydrogen ions and when the blood becomes too alkaline, the kidneys excrete fewer hydrogen ions. This helps to maintain the pH within the normal range of 7.35-7.45. The other electrolytes listed, such as calcium, sodium, magnesium, and potassium, do not directly regulate pH and their excretion is not primarily responsible for pH balance.
