Hypothyroidism is a condition that occurs if the thyroid gland does not produce enough of the thyroid hormone. A) have hormone receptors. E) Addison's disease. E) little glucagon. The hormone also seems to decrease the amount of calcium the kidneys can re-absorb, lowering levels further. Calcitonin also regulates the level of calcium and other mineral levels in the kidneys. To this end, this protein prevents the reabsorption of phosphate by the kidney and increases the kidneys reabsorption of calcium and magnesium, thus leading to increased calcium excretion via the urine. D) STH. A) the rate of glucose synthesis by the liver.
