The parathyroid glands are two pairs of small, oval-shaped glands located adjacent to the two thyroid gland lobes in the neck.
Function of the parathyroid glands
Parathyroid glands produce parathyroid hormone, which plays a key role in the regulation of calcium levels in the blood. Precise calcium levels are important in the human body, since small deviations can cause muscle and nerve impairment.
The parathyroid hormone stimulates the following functions:
Release of calcium by bones into the bloodstream
Absorption of calcium from food by the intestines
Conservation of calcium by the kidneys
