Parathyroid Glands: Essentials. 1  Parathyroid hormone regulates the bodyâs calcium levels. 2  There are four parathyroid glands, and they are each about the size of a grain of rice.3  Though theyâre located near each other, the parathyroid glands are not related to the thyroid gland. PTH regulates how much calcium is absorbed from your diet, how much calcium is excreted by your kidneys, and how much calcium is stored in your bones. 2  We store many pounds of calcium in our bones, and it is readily available to the rest of the body at the request of the parathyroid glands.
The parathyroid hormone regulates the blood levels of calcium. The hormone helps keep the calcium levels constant as it acts on kidneys, intestines and bones. Continue Reading. Maintaining a level blood calcium concentration is crucial to the function of nerves and muscle contractions. The parathyroid hormone, or PTH, is excreted from the parathyroid glands when blood calcium levels drop. The bones, intestines and kidneys are targeted during the release of PTH. The function of PTH varies, but in general, the hormone helps to stimulate reabsorption of the calcium and acts as a trigger to increase calcium absorption in the intestines. When the blood calcium levels rise, the PTH release is inhibited.
