The parathyroid gland's main function is to maintain the calcium-phosphorus balance in the body through the release of parathyroid hormone (PTH). PTH acts on various body systems to regulate blood calcium levels.
The primary function of the parathyroid gland is to maintain the calcium-phosphorus balance in the body by regulating blood calcium levels. When blood calcium levels drop, the parathyroid gland releases parathyroid hormone (PTH), which acts on the kidneys to enhance calcium reabsorption, stimulates bone breakdown to release calcium, activates vitamin D for gastrointestinal calcium absorption, and promotes calcium uptake by the kidneys.
