Quizplus · Accepted Answer

Both the kidneys and the lungs are considered physiological pH control mechanisms. The kidneys regulate the pH of the blood by excreting or retaining hydrogen ions and bicarbonate ions, while the lungs regulate the pH through the elimination or retention of carbon dioxide. Additionally, the buffers in the blood help to maintain a stable pH by binding to excess hydrogen or hydroxide ions.
