    production of each hormone is kept balanced by the feedback mechanism between the individual gland (the thyroid, for example), the hypothalamus, and the pituitary gland. If a gland overproduces or underproduces a hormone, the master glands register this from the amount of hormone in the bloodstream. The master glands then respond by regulating the hormonal production. The system works with great precisior; despite the fact tat the hormones are transported in the bloodstream and are disseminated…
