Detailed explanation-1: -Parathyroid hormone is secreted from four parathyroid glands, which are small glands in the neck, located behind the thyroid gland. Parathyroid hormone regulates calcium levels in the blood, largely by increasing the levels when they are too low.
Detailed explanation-2: -The parathyroid glands lie behind the thyroid. They produce parathyroid hormone, which plays a role in regulating the body’s blood level of calcium and phosphorus. Hyperparathyroidism is when your parathyroid glands create high amounts of parathyroid hormone in the bloodstream.
Detailed explanation-3: -Like all endocrine glands, parathyroids make a hormone (a small protein capable of causing distant cells in the body to react in a specific manner). Parathyroid hormone (PTH) has a very powerful influence on the cells of the bones which causes them to release their calcium into the bloodstream.
Detailed explanation-4: -As a rule, if the calcium level in the blood is low, the parathyroid glands sense this and release PTH. PTH then causes release of calcium from the bones into the bloodstream, increases vitamin D production from the kidney which ultimately increases absorption of calcium from the intestines.
Detailed explanation-5: -Parathyroid hormone comes from four parathyroid glands in the neck, just behind the thyroid. These glands receive feedback from blood calcium levels to determine when they need to secrete the hormone.
