Question

Quizplus · Accepted Answer

Parathyroid hormone (PTH) is the most important regulator of calcium levels in the blood. PTH is produced by the parathyroid glands and acts on the bones, kidneys, and intestines to increase calcium levels in the blood. It promotes the release of calcium from bones, reabsorption of calcium in the kidneys, and absorption of calcium in the intestines. This helps to maintain appropriate calcium levels in the blood for proper nerve and muscle function, as well as maintenance of bone health. The other hormones listed do not have as significant of a role in regulating calcium levels in the blood.
