| 释义 | adrenaline (once / 14004 pages) n If you've ever been in a car that screeched to a stop, barely avoiding an accident, you probably felt a surge of adrenaline that left your heart pounding. Adrenaline is a hormone that's released in response to stressful situations. Adrenaline was named after the gland in the human body that releases it, the adrenal gland. The body secretes adrenaline when danger or stress is present, as a kind of safety measure; when adrenaline is released in your body, you feel your heart beat faster and a sudden rush of energy which might give you the strength to fight off an attacker or flee a dangerous animal.
