The parathyroid hormone (PTH) is secreted by the parathyroid gland, four small glands located on the posterior surface of the thyroid gland. The hormone is regulated by the calcium and phosphate levels in the blood and acts primarily on the bone and kidneys to increase circulating levels of calcium.
In the kidney, parathyroid hormone (PTH) blocks reabsorption of phosphate in the proximal tubule while promoting calcium reabsorption in the ascending loop of Henle, distal tubule, and collecting tubule.Parathyroid hormone (PTH) promotes absorption of calcium from the bone in 2 ways.The rapid phase brings about a rise in serum calcium within minutes and appears to occur at the level of the osteoblasts and osteocytes.hen parathyroid hormone (PTH) binds to receptors on these cells, the osteocytic membrane pumps calcium ions from the bone fluid into the extracellular fluid. The slow phase of bone resorption occurs over several days and has 2 components.
