The parathyroid hormone regulates the blood levels of calcium. The hormone helps keep the calcium levels constant as it acts on kidneys, intestines and bones. Continue Reading. Maintaining a level blood calcium concentration is crucial to the function of nerves and muscle contractions. The parathyroid hormone, or PTH, is excreted from the parathyroid glands when blood calcium levels drop. The bones, intestines and kidneys are targeted during the release of PTH. The function of PTH varies, but in general, the hormone helps to stimulate reabsorption of the calcium and acts as a trigger to increase calcium absorption in the intestines. When the blood calcium levels rise, the PTH release is inhibited.
The level of calcium in blood is regulated primarily by two hormones: parathyroid hormone and calcitonin. Parathyroid hormone is produced by the four parathyroid glands, located around the thyroid gland in the neck. When the calcium level in blood decreases, the parathyroid glands produce more parathyroid hormone.timulates the digestive tract to absorb more calcium. Causes the kidneys to activate vitamin D, which enables the digestive tract to absorb more calcium. Calcitonin is produced by cells of the thyroid gland. It lowers the calcium level in blood by slowing the breakdown of bone, but only slightly.
