Question

Quizplus · Accepted Answer

Calcitriol, also known as activated vitamin D, is a steroid hormone that is synthesized from pre-vitamin D3 in the skin and then converted to calcitriol by enzymes in the liver and kidneys. The synthesis and secretion of calcitriol by the kidneys is stimulated by parathyroid hormone (PTH), which is released by the parathyroid gland in response to low levels of calcium in the blood. Calcitriol acts to increase calcium absorption in the intestines, reduce calcium excretion by the kidneys, and stimulate calcium release from bones, thereby raising blood calcium levels.
