Respuesta :
The enzyme that converts the vitamin D your skin produces from sun exposure into calcitriol is stimulated by parathyroid hormone. By inhibiting the breakdown of bone-calcium and calcium from being reabsorbed by the kidneys, calcium levels are decreased by calcitonin.
The production of parathyroid hormone by the parathyroid glands is essential for controlling blood calcium levels. The human body needs precise calcium levels since even tiny variations can lead to issues with muscles and nerves.
The major function of calcitonin is to reduce blood calcium levels (not your bones). It accomplishes this in two ways: Osteoclasts are cells that tear down bone, and calcitonin inhibits (blocks) their activity. Your circulation receives calcium from your bones when osteoclasts break them down.
