Question

Quizplus · Accepted Answer

Calcitonin is a hormone that is produced by the thyroid gland and acts to temporarily lower blood calcium levels. It does this by promoting calcium deposition in bones and decreasing calcium absorption in the kidneys and intestines. When administered in large doses, it can have a significant effect in lowering blood calcium levels, making it a useful treatment for hypercalcemia (excessively high blood calcium levels).
