Question

TestHub · Accepted Answer

Parathormone or parathyroid hormone is produced and secreted by the parathyroid glands and their main function is to regulate serum calcium concentration by increasing the calcium levels in the blood. Calcium plays an important role in blood clotting and therefore if it is deficient there will be a delay in the clotting process. Thyroxine regulates metabolic processes of the body and adrenaline and nor-adrenaline are hormones of the sympathetic nervous system.
