00:00 / 00:00
Video Summary
Parathyroid hormone (PTH) is a hormone produced by the parathyroid glands and plays a crucial role in regulating the balance of calcium in the body. This hormone is released when the calcium-sensing receptor on parathyroid cells detects a decrease in extracellular calcium.
PTH increases the level of calcium in the blood, by stimulating the bones to release calcium, increasing the absorption of calcium from food in the intestines, and decreasing the excretion of calcium by the kidneys.
