They are found above the kidneys . Each gland has an outer cortex which produces steroid hormones and an inner medulla . The adrenal cortex itself is divided into three zones: the zona glomerulosa, the zona fasciculata and the zona reticularis . </P> <P> The adrenal cortex produces three main types of steroid hormones: mineralocorticoids, glucocorticoids, and androgens . Mineralocorticoids (such as aldosterone) produced in the zona glomerulosa help in the regulation of blood pressure and electrolyte balance . The glucocorticoids cortisol and corticosterone are synthesized in the zona fasciculata; their functions include the regulation of metabolism and immune system suppression . The innermost layer of the cortex, the zona reticularis, produces androgens that are converted to fully functional sex hormones in the gonads and other target organs . The production of steroid hormones is called steroidogenesis, and involves a number of reactions and processes that take place in cortical cells . The medulla produces the catecholamines adrenaline and noradrenaline, which function to produce a rapid response throughout the body in stress situations . </P>

An organ that produces secretions called hormones is known as a
