Calcium Homeostasis: Regulation & Maintenance
Extracellular calcium is transported throughout the body via the blood vessels. Two primary factors are responsible for stabilizing blood calcium levels: the parathyroid hormone, in short PTH, which forms in the parathyroid glands, and vitamin D, which is synthesized in the liver and skin and converted into its active form, calcitriol, in the kidney. A third regulator is calcitonin, which forms in the thyroid gland.

Great video, thanks for the upload.
I have to listen to this one several times before listening to the more advanced videos out there. Very good primer!
I have previously struggled with trying to understand the calcium and phosphate regulation. But not anymore. Thank you for this video.
