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 glands are most often found behind the thyroid gland in the neck. The parathyroid glands control the level of calcium in the blood by making parathyroid hormone (PTH). This is a chemical messenger that tells the body how to control calcium.o increase the blood calcium level, the body may absorb more calcium from food in the intestines. It may also take calcium from the bones. When the blood calcium level is high, the glands make less PTH. This tells the body to decrease the amount of calcium in the blood.
