Quizplus · Accepted Answer

The description given refers to the fight-or-flight response, which involves a physiological reaction to a perceived threat or stressor, preparing the body for action to either fight the threat or flee from it. It is not a negative or positive feedback response as those relate to processes that regulate themselves, whereas the fight-or-flight response is a reaction to an external stimulus. It also temporarily disrupts homeostasis by shifting physiological processes into high gear to deal with the perceived threat.
