These epithelial cells produce and secrete the parathyroid hormone (PTH), the major hormone involved in the regulation of blood calcium levels. Parathyroid Glands The small parathyroid glands are embedded in the posterior surface of the thyroid gland.
Normal Parathyroid Gland Function. How Parathyroid Glands Work. Parathyroid glands control the calcium in our blood and bones. Learn how parathyroid glands work by making parathyroid hormone to control blood and bone calcium.This page of Parathyroid.com discusses the normal function of parathyroid glands, how parathyroid glands monitor and control blood calcium and what it means to have high blood calcium.he four parathyroid glands make more or less parathyroid hormone (PTH) in response to the level of calcium in the blood. When the calcium in our blood goes too low, the parathyroid glands make more PTH. Increased PTH causes the body to put more calcium into the blood.
