When the kidney secretes hydrogen ions

Question

Quizplus · Accepted Answer

When the kidney secretes hydrogen ions, it does so primarily to regulate the body's pH balance by removing excess acidity from the blood. This process does not inherently raise the pH of the urine, add sodium ions to the urine, or add bicarbonate ions to the urine. Instead, the secretion of hydrogen ions can lead to the formation of new bicarbonate ions in the blood, helping to neutralize the blood's pH, but this bicarbonate is not added to the urine as part of the hydrogen ion secretion process.
