    Also known as epinephrine, adrenalin is a naturally occurring hormone. During the  fight-or-flight response, the adrenal gland releases adrenalin into the blood stream, along with other hormones like cortisol, signaling the heart to pump harder, increasing blood pressure, opening airways in the lungs, narrowing blood vessels in the skin and intestine to increase blood flow to major muscle groups, and performing other functions to enable the body to fight or run when encountering a perceived threat.
