6. Hormone Regulation
6.1 Calcium Ion and Parathyroid Hormone
Calcium ion plays a crucial role in the regulation of parathyroid hormone (PTH), a hormone secreted by the parathyroid glands. When blood calcium levels drop, calcium-sensing receptors in the parathyroid glands detect this decrease and stimulate the release of PTH into the bloodstream. PTH then acts on various tissues and organs to increase calcium absorption from the gut, promote calcium release from bones, and enhance kidney reabsorption of calcium. This intricate feedback mechanism helps maintain stable calcium ion levels in the body.
6.2 Calcium in Vitamin D Metabolism
Calcium is intimately involved in the metabolism of vitamin D, a hormone that regulates calcium absorption and utilization. When sunlight or dietary sources activate vitamin D, it undergoes a series of conversions in the liver and kidneys, ultimately becoming its active form, calcitriol.
