Explain the Functions of Parathyroid Gland

The main function of the parathyroid gland is to regulate the calcium levels in our body so that the nervous and muscular functions (where calcium has an important role) can function properly. Parathyroid hormone is mainly responsible for:

Maintaining the constancy of plasma calcium (9 to 11 mg %). It has a direct effect on bone from which calcium resorption occurs.
Promoting absorption of calcium from the small intestine. But this is brought about mainly by controlling the production of 1, 25-dihydroxycholecalciferol in the renal tubules.
