Q

The hormones PTH and calcitonin produced by the parathyroid gland function to regulate calcium within the blood. Explain how each works to control calcium levels in the blood.

A

Parathyroid secretes PTH when calcium levels are high. Thyroid — calcitonin —- lowers blood calcium (osteoblast) —- build up
Parathyroid secretes less pTH when calcium levels are low. Parathyroid — PTH — raises blood calcium (osteoclasts)
