Overview of Parathyroid Function
The parathyroid glands secrete parathyroid hormone (PTH), which regulates calcium levels in the blood and tissues through its effects on bones, the kidneys, and the intestine. PTH raises the level of calcium in the blood when the level of calcium is too low (a condition called hypocalcemia).
Parathyroid hormone (PTH), also known as parathormone or parathyrin, is a peptide hormone secreted by the parathyroid glands. It plays a critical role in regulating serum calcium and phosphate levels through its actions on bone, kidneys, and the small intestine.
Parathyroid Gland
The primary function of the parathyroid glands is to produce and secrete parathyroid hormone (PTH) in response to low blood calcium levels . PTH increases blood calcium by promoting calcium release from bones, enhancing calcium reabsorption in the kidneys, and increasing calcium absorption from the small intestine.
Parathyroid hormone is an important hormone that's in charge of managing your blood calcium levels . If you're experiencing symptoms of hypercalcemia or hypocalcemia, like issues with your muscles and mental function , it's important to contact your healthcare provider.
Parathyroid Glands
Function What is the function of the parathyroid glands? Your parathyroid glands have one job: making and releasing parathyroid hormone (PTH). Together, PTH and another hormone — calcitonin — tightly control the levels of calcium in your bloodstream. Having too much or too little calcium in your blood can be associated with health issues.
The parathyroid gland is a type of endocrine gland that occurs in the upper and lower poles of the thyroid gland. There are four parathyroid glands.

Explore the parathyroid glands, their anatomy, location, and role in calcium regulation. Learn about parathyroid hormone (PTH), physiological functions , and related clinical conditions.
These hormones play an important role in regulation of your weight, energy levels , internal temperature, skin, hair, nail growth, metabolism and is an important part of the endocrine system. Although it gets less attention than thyroid hormones , the parathyroid hormone is still important in the body.
17.5 The Parathyroid Glands
The parathyroid glands produce and secrete PTH, a peptide hormone , in response to low blood calcium levels (Figure 17.5.2). PTH secretion causes the release of calcium from the bones by stimulating osteoclasts, which secrete enzymes that degrade bone and release calcium into the interstitial fluid.
There are typically 4 parathyroid glands. As the name implies, they are located near the thyroid gland in the neck, although the number and particularly the location are quite variable. These pea-sized glands play a vital role in maintaining the body's calcium level . (See also Hypercalcemia and Hypocalcemia.) Parathyroid cells manufacture, store, and secrete a polypeptide hormone called ...
