The adrenal gland is a small gland located on top of the kidneys that releases hormones involved in stress response and regulation of bodily functions.
This hormone released by the adrenal gland helps regulate stress responses and plays a role in metabolism.
Epinephrine (Adrenaline): Another hormone released by the adrenal gland that increases heart rate, blood pressure, and prepares the body for 'fight or flight' response.
Aldosterone: This hormone released by the adrenal glands helps regulate blood pressure by controlling sodium and potassium levels in the body.
