Calcium and Phosphate Homeostasis
Facilitates mobilization of calcium and phosphate from bone. To prevent detrimental increases in phosphate, parathyroid hormone also has a potent effect on the kidney to eliminate phosphate (phosphaturic effect). Maximizes tubular reabsorption of calcium within the kidney. This activity results in minimal losses of calcium in urine.
