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).

Step 1
These are parathyroid hormone (PTH) and calcitonin. Additionally, note that vitamin D (in its active form, calcitriol) also plays a role, but it is not a primary hormone in the negative feedback loop. Show more…

a. List three organ systems involved in the maintenance of blood calcium levels, and state the role of each organ system in the process. b. Is blood calcium regulation an example of negative feedback control or positive feedback control? Explain.

The hormone calcitonin is released from the thyroid gland in response to increased levels of calcium ions in the blood. If blood calcium levels are controlled by negative feedback, what effect would calcitonin have on blood calcium levels? Please explain your answer. Is calcitonin the effector, control center, or receptor?
Calcium levels in Mr. Gallariani's blood are dropping to dangerously low levels. The hormone PTH is released and soon blood calcium levels begin to rise. Shortly after, PTH release slows. Is this an example of a positive or negative feedback mechanism? What is the initial stimulus? What is the result?
