Question

Quizplus · Accepted Answer

Parathyroid hormone (PTH) is released by the parathyroid glands in response to low blood calcium levels. PTH increases blood calcium levels by stimulating bone resorption, increasing calcium reabsorption in the kidneys, and activating vitamin D synthesis which increases calcium absorption in the gut. PTH has no direct effect on blood phosphate levels or vitamin D production. Therefore, only choice A is correct.
