Science glossary film: Adrenaline

Also called epinephrine, a hormone produced by the adrenal glands, which are found just above the kidneys. Adrenaline has powerful effects on the body, increasing heart rate, boosting the power of muscles, and increasing the rate and depth of breathing. It rapidly prepares the body for a 'flight or flight' response to threat, allowing it to perform above normal levels over short periods.
