Answer: The Parathyroid gland
Explanation:
The Parathyroid gland secretes "Parathormone", an hormone that exerts
- direct influence on the bone by INCREASING the release of bone calcium ion (Ca2+) into the blood
- affects the kidney by stimulating the renal tubules to eliminate EXCESS calcium in the urine.
Thus, the calcium balance of the body depends on the secretion of the Parathyroid gland
