Karen is experiencing the fight-or-flight response that is activated by the sympathetic nervous system.

The fight-or-flight response alludes to a physiological response that happens within the sight of something that is startling, either mentally or physically. The reaction is activated by the arrival of hormones that set up your body to either stay and manage a danger or to flee to security or safety. The sympathetic nervous system begins in the spinal cord and its fundamental capacity is to initiate the physiological changes that happen during the fight-or-flight response.
