Quizplus · Accepted Answer

The symptoms described (heart racing, rapid breathing, dry mouth, cold and clammy skin) are indicative of the body's fight-or-flight response, which is controlled by the sympathetic branch of the autonomic nervous system. This response prepares the body to either fight or flee from an immediate threat, in this case, the injury.
