The parathyroid glands secrete PTH, a substance that helps maintain the correct balance of calcium and phosphorus in the body. PTH regulates the level of calcium in the blood, release of calcium from bone, absorption of calcium in the intestine, and excretion of calcium in the urine.he parathyroid glands constantly measure calcium levels in your blood. If the calcium level gets too high, the normal glands sense this and stop production of PTH. This lowers the calcium in your body and returns your calcium levels to normal. Abnormal glands cannot regulate calcium balance.
The parathyroid hormone (PTH) is secreted by the parathyroid gland, four small glands located on the posterior surface of the thyroid gland.The hormone is regulated by the calcium and phosphate levels in the blood and acts primarily on the bone and kidneys to increase circulating levels of calcium.Over-or underactivity of the parathyroid gland ultimately impacts on the blood and urine calcium levels due to an excess or deficiency of parathyroid hormone.f there is any chronic deficiency of calcium, the parathyroid gland will expand in size (hypertrophy) to compensate for sustained PTH secretion. Conversely, a persistent elevation in the calcium levels will cause the parathyroid glands to shrink in size.
