GENERAL HISTOLOGY

Detailed explanation-1: -Parathyroid hormone decreases phosphate reabsorption at the proximal convoluted tubule. Phosphate ions in the serum form salts with calcium that are insoluble, resulting in decreased plasma calcium. The reduction of phosphate ions, therefore, results in more ionized calcium in the blood.

Detailed explanation-2: -Parathyroid hormone (PTH) is a hormone that your parathyroid glands make and release to control the level of calcium in your blood by increasing it. PTH also helps control the levels of phosphorus (a mineral) and vitamin D (a hormone) in your blood and bones.

Detailed explanation-3: -One or more of the parathyroid glands produces high amounts of parathyroid hormone. This leads to high calcium levels and low phosphorus levels in your blood.

Detailed explanation-4: -Parathyroid hormone (PTH) is a hormone your parathyroid glands release to control calcium levels in your blood. It also controls phosphorus and vitamin D levels. If your body has too much or too little parathyroid hormone, it can cause symptoms related to abnormal blood calcium levels.

Detailed explanation-5: -If calcium decreases, the parathyroid glands sense the decrease and secrete more parathyroid hormone. The parathyroid hormone stimulates calcium release from the bones and increases the calcium uptake into the bloodstream from the collecting tubules in the kidneys.
