Quizplus · Accepted Answer

Calcitonin is a hormone that regulates calcium levels in the blood. When the amount of calcitonin in the blood increases, the amount of calcium in the blood decreases because it promotes the uptake of calcium by the bones and reduces calcium release from the bones. Therefore, option C is the correct choice. Option A is incorrect because the increase in calcitonin level does not lead to an increase in calcium in the blood. Option B is also incorrect because the increase in calcitonin level leads to decreased release of calcium from the bones.
