Quizplus · Accepted Answer

PTH (parathyroid hormone) is responsible for regulating calcium ion levels in the blood. An increase in PTH levels will lead to the release of calcium from bone tissue and a decrease in calcium excretion by the kidneys, ultimately leading to an increase in calcium ion levels in the blood.
