The fight-or-flight response is a physiological reaction that occurs in response to a perceived threat, preparing the body to either confront or flee from danger. This process involves the activation of the autonomic nervous system and the release of stress hormones, particularly adrenaline, which together enhance physical performance and increase alertness. Understanding this response is crucial for recognizing how the body reacts under stress and the role of specific glands, such as the adrenal glands, in this rapid response mechanism.
