Definition:
Parathyroid hormone (PTH) is secreted by the parathyroid glands. Its job is to regulate the amount of calcium and phosphorous available in the blood.
In general, parathyroid hormone:
- Raises the level of calcium in the blood
- Decreases the level of phosphorous in the blood
- Increases the amount of active vitamin D available in the body
Parathyroid hormone is closely linked to vitamin D, and both of these substances likely play a role in the long-term regulation of blood pressure.
Also Known As: PTH
