    Answer is (B). The hormone participates in calcium (Ca2+) and phosphorus metabolism. In many ways, calcitonin counteracts parathyroid hormone (PTH) and vitamin. More specifically, calcitonin lowers blood Ca2+ levels in two ways: Major effect: Inhibits osteoclast activity in bones, which break down the bone. Minor effect: Inhibits renal tubular cell reabsorption of Ca2+ and phosphate, allowing them to be excreted in the urine. An osteoclast is a type of bone cell that breaks down bone tissue. This function is critical in the maintenance, repair, and remodelling of bones of the vertebral skeleton.
