Adrenal Gland Diagram
Adrenal Glands. What You Need to Know. Adrenal glands, also known as suprarenal glands, are small, triangular-shaped glands located on top of both kidneys. Adrenal glands produce hormones that help regulate your metabolism, immune system, blood pressure, response to stress and other essential functions.
Each adrenal gland has a covering (capsule). The adrenal cortex produces several hormones. The most important are aldosterone (a mineralocorticoid), cortisol (a glucocorticoid), and androgens and estrogen (sex hormones).
The adrenal medulla is located inside the adrenal cortex in the center of an adrenal gland. It produces “stress hormones,” including adrenaline. The adrenal cortex and adrenal medulla are enveloped in an adipose capsule that forms a protective layer around an adrenal gland. Hormones of the Adrenal Glands
