Adrenal glands are small glands (groups of cells that can produce and release substances such as hormones into the bloodstream) that sit on top of both kidneys. They produce several hormones to regulate the function of the metabolism, immune system, and the response to stress, including Cortisol (which regulates the metabolism and reaction to stress), Adrenaline (the “stress hormone” which leads to fight or flight reactions), and gonadocortioids (sex hormones).
