Quizplus · Accepted Answer

The calcium and phosphate balances are primarily regulated by parathyroid hormone, calcitonin, and vitamin D. Parathyroid hormone increases calcium levels and decreases phosphate levels in the blood, while calcitonin does the opposite. Vitamin D plays a role in both calcium and phosphate absorption in the intestines and their reabsorption in the kidneys. Therefore, option B, which includes parathyroid hormone, calcitonin, and vitamin D, is the best choice for substances that influence calcium and phosphate balances.
