Peptide chain

Ways Parathyroid Raises the Calcium Level:1.Breaking down bone to release calcium2.Helps the body absorb calcium from food3.Increase the kidney’s ability to retain calcium

FUNCTION OF THE HORMONE

The thyroid gland is similar to a thermostatMaintains a strict level of calcium in the

bloodIf the calcium level is too low, the hormone

hormone stops
