This gland is composed of the adrenal cortex and the adrenal medulla, both of which have different functions. The adrenal cortex secretes three different groups of hormones: (1) Mineralocorticoids – mainly aldosterone, (2) Glucocorticoids – mainly Cortisol or hydrocortisone, and (3) Sex Hormones – resemble testosterone. Mineralocorticoids help to control that amount of minerals salts (sodium and potassium) in the blood.
