What is a correct statement about the function of the hormones involved in blood calcium homeostasis?

Question

Quizplus · Accepted Answer

Calcitonin acts to lower blood calcium levels, whereas parathyroid hormone acts to raise blood calcium levels. This is the opposite function of what is described in option A. Option B is incorrect because it is the parathyroid gland, not the thyroid gland, that releases parathyroid hormone in response to falling blood calcium levels. Option D is incorrect because it describes both hormones acting to raise blood calcium levels, which is an oversimplification.
