Parathyroid hormone (PTH) regulates blood calcium levels by stimulating osteoclasts, affecting kidney function, and initiating calcitriol production.
Parathyroid hormone (PTH) plays a crucial role in regulating blood calcium levels. However, PTH does not act on the parafollicular cells of the thyroid gland to increase the level of the hormone calcitonin. Instead, PTH stimulates osteoclasts, affects kidney function, and initiates the production of calcitriol for this purpose.
