When blood calcium levels drop to a certain threshold level in humans, calcitonin release is no longer stimulated, which stops bone cells from releasing calcium into the blood. What of the following statements is most likely true of this coordinated response? A. Regulation of calcium in blood is essentially a genetically controlled mechanism that keeps calcium levels constant. B. Bone cells control calcium levels by either absorbing or releasing calcium in response to dietary calcium intake. C. Calcium is under positive feedback control so the body does not deplete its bone calcium reserves. D. This negative feedback mechanism involves endocrine organs and bone cells in balancing calcium distribution in the body.

Identify the two negative feedback loops that control calcium levels in the blood. Ensure that you can identify the receptor, control center and effector for each feedback loop. (we are aware that one hormone is only shown to affect calcium levels when given at high doses).
