Question

Write short on the functions of the parathyroid hormone.

Answer 1

The principal/chief cells of the parathyroid produce the parathyroid hormone also called the parathormone. The function of this hormone are as follows :

• To maintain calcium and phosphate balance in the blood and other tissues.
• To increase calcium reabsorption from the intestine as well as from the nephrons of the kidney.
• To initiate bone resorption (e.g. reabsorption of calcium from bones), in case the blood calcium levels drop.
