Quizplus · Accepted Answer

The kidneys play a major role in regulating blood phosphorus levels by filtering excess phosphorus out of the blood and excreting it in urine or reabsorbing it back into the blood as needed. Intestinal absorption and metabolism of phosphorus and thyroid hormone levels can also influence blood phosphorus levels to a lesser extent, but the kidneys are the primary regulators. The liver does not play a significant role in phosphorus regulation.
