How do the parathyroid glands function in opposition to the thyroid glands?
What will be an ideal response?
The thyroid gland C cells secrete calcitonin, a hormone that targets the bones, kidneys, and intestines to decrease the calcium ion concentrations in the body fluids. The parathyroid gland chief cells secrete parathyroid hormone, which targets the same organs as does calcitonin but increases calcium ion concentrations. In balance, the two hormones regulate calcium levels in the body.
