Parathyroid hormone (PTH) is secreted from four parathyroid glands situated behind the thyroid gland. PTH regulates calcium and phosphate levels by its promotion of phosphate excretion and calcium reabsorption in the kidneys; stimulation of osteoclastic activity in the bone resulting in raised serum calcium; and increased intestinal absorption of calcium.
