Final answer:
Parathyroid hormone (PTH) promotes the reabsorption of phosphate by the kidneys and inhibits its excretion. This helps lower blood phosphate levels and maintain calcium homeostasis.
Step-by-step explanation:
Parathyroid hormone (PTH) promotes the reabsorption of phosphate by the kidneys, not its excretion. PTH inhibits the reabsorption of phosphate by the renal tubules, allowing it to be lost in the urine.
This helps lower blood phosphate levels and promotes the reabsorption of calcium by the kidneys, maintaining calcium homeostasis in the body. Parathyroid hormone (PTH) promotes the reabsorption of phosphate by the kidneys and inhibits its excretion. This helps lower blood phosphate levels and maintain calcium homeostasis.
