Calcitonin and parathormone. Hormonal regulation of blood calcium levels. Regulation of calcium levels in the blood by CT from the thyroid gland and by PTH from the parathyroid glands. Too much calcium could cause heart failure, while low calcium could cause loss of nervous system control. Thyroid structure vectors
