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.
Calcium levels are controlled by the thyroid and parathyroid. Thyroid gland releases a hormone known as calcitonin when Ca levels are high, promoting Ca uptake by bone.
