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 level of calcium in blood is regulated primarily by two hormones: parathyroid hormone and calcitonin. Parathyroid hormone is produced by the four parathyroid glands, located around the thyroid gland in the neck. When the calcium level in blood decreases, the parathyroid glands produce more parathyroid hormone.timulates the digestive tract to absorb more calcium. Causes the kidneys to activate vitamin D, which enables the digestive tract to absorb more calcium. Calcitonin is produced by cells of the thyroid gland. It lowers the calcium level in blood by slowing the breakdown of bone, but only slightly.
