The adrenal glands, or adrenals, are two small glandular organs located above the upper pole of each kidney (hence their name, precisely sur-renal).
They have a triangular shape and are formed by several components.
The central part, called the medulla of the adrenal gland, produces two chemicals that have important functions in the central nervous system: adrenaline and noradrenaline. The outer part is called the cortical and produces steroid hormones, including aldosterone, which helps regulate blood pressure, cortisol, which is important in regulating blood sugar levels (blood sugar), some male (androgen) and female ( estrogen precursors) sex hormones.
