Question

Quizplus · Accepted Answer

When blood pH is too low (acidic), the kidneys will secrete excess hydrogen ions into the urine to decrease the acidity of the blood and restore a healthier balance. Option A is incorrect because sodium ions are not directly involved in regulating blood pH. Option B is incorrect because reabsorbing more hydrogen ions from the filtrate would further decrease blood pH, rather than restoring a healthier balance. Option D is incorrect because slowing ventilation would result in an accumulation of carbon dioxide, which would further lower blood pH.
