Question

Quizplus · Accepted Answer

PTH (parathyroid hormone) is produced by the parathyroid gland and increases the blood calcium level by stimulating the release of calcium from bones and increasing calcium reabsorption in the kidneys. Thyroxine (A) is produced by the thyroid gland and regulates metabolism. Calcitonin (C) is also produced by the thyroid gland but has the opposite effect of PTH, lowering the blood calcium level by inhibiting calcium release from bones and increasing calcium excretion in the kidneys. Insulin (D) is produced by the pancreas and regulates glucose metabolism, not calcium levels.
