Question

Quizplus · Accepted Answer

Parathyroid hormone (PTH) is made in the parathyroid glands, not the thyroid gland. PTH increases the amount of calcium in the blood by stimulating the release of calcium from bones and increasing the reabsorption of calcium by the kidneys. PTH does not decrease the amount of calcium in the blood. While PTH does play a role in regulating bone metabolism, it does not stimulate the formation of bone; rather, it stimulates bone resorption to release calcium into the bloodstream.
