A member asked:

How can blood calcium be regulated, and how are our bones affected in the process?

A doctor has provided 1 answer

Three company: Parathyroid hormone, it raises the levels of calcium in the blood through multiple pathways. The effect of the hormone calcitonin, which the c cells of your thyroid gland secrete, opposes that of parathyroid hormone. It decreases the levels of calcium in your blood by increasing the deposition of calcium in the bones. Vitamin d causes absorption of calcium from the intestine.
