What is the purpose of the Parathyroid Glands?
There are four tiny parathyroid glands which are located on the posterior side of the thyroid gland which have two on each lobe. The parathyroid glands secrete parathyroid hormones which regulates the amount of calcium in the blood. If the calcium is too low, parathyroid hormone moves calcium from the bones to the blood. Parathyroid hormone actually has an opposite action from that of calcitonin secreted by the thyroid gland.
