WebThe parathyroid glands make parathyroid hormone (PTH). This hormone controls blood calcium levels. Calcium is very important for proper functioning of bones, muscles and nerves. In the normal state, PTH is secreted whenever blood calcium gets too low. PTH helps absorb calcium from the gut and releases it from bones.
The plasma ionized calcium concentration is regulated within narrow limits (1.3–1.5 mmol/L).
