Question

Define the role that calcium, Calcitriol, and parathyroid hormone play in bone remodeling

Answer 1

Bone remodeling is the process by which the mature bone tissue is removed and new bone tissues are formed. The mature bone tissue is the osteoclast. Parathyroid hormone is stimulated when blood level of calcium is at low level. So at the time of new bone formation the calcium level is necessary. For forming new tissues, the parathyroid hormone males the mature tissues to break-down and release the vacuum into the blood. The strength of the bone is made by the calcium. Calcium is the main component of the bones. Bone remodeling itself can be told as the calcium homeostasis mechanism. Calcitriol isa hormone that allows the bone to take the calcium by reasbsorbing from urine. So when parathyroid hormone breaks the tissues and release the calcium to blood the calcitonin makes the newly forming tissues to absorb the calcium necessary for them to grow. The serum plasma calcium levels is maintained by the calcitriol
