Parathyroid Gland and Its functions

What are Parathyroid Glands?
Parathyroid glands are four small glands of the endocrine system which regulate the calcium in our bodies. Parathyroid glands are located in the neck behind the thyroid where they continuously monitor and regulate blood calcium levels.

What do Parathyroid Glands do?
Parathyroid glands control the calcium levels in our blood, in our bones, and throughout our body. Parathyroid glands regulate the calcium by producing a hormone called Parathyroid Hormone (PTH). Calcium is the most important element in our bodies (we use it to control many organ systems), so calcium is regulated more carefully than any other element. In fact, calcium is the only element with it's own regulatory system -- the parathyroid glands.
