B) respiratory rate increases. Calcium is one of the most important minerals in your body. Release of calcitonin and hypoalbuminemia are two proposed reasons. Primary, PTH stimulates osteoblasts leading to increase RANKL (receptor activator for nuclear factor kappa-B ligand) expression and thus differentiation of osteoclasts. The synthesis of calcitriol is completed in the kidneys, parathyroid hormone (PTH) is secreted by the parathyroid glands, and The thyroid gland releases triiodothyronine (T3) and thyroxine (T4). Release of calcitonin and hypoalbuminemia are two proposed reasons. PTH maintains the balance between calcium and: sodium., The hormone that raises blood sugar levels is glucagon.
