Which of the following regulates the level of calcium in the blood?

Question

Answer 1

mm, the parathyriod hormone comes up number one in calcium regulation, but calcitonin in either hi or low blood lvls doesnt effect calcium lvls much at all, at least according to righthealth.com, so im not really sure, none of the other answers comes close enuf to qualify as correct so i'd have to go with d, but its a crummy answer.

Answer 3
