The fight or flight response is a physiological reaction triggered by the sympathetic nervous system in response to a perceived threat or stressor. It prepares the body to either confront the threat or flee from it by increasing heart rate, dilating pupils, and releasing stress hormones like adrenaline. This response is essential for survival in dangerous situations.
Fight or flight response is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. It triggers a cascade of hormonal and physiological responses to prepare the body to either confront the threat (fight) or flee from the situation (flight). This response is essential for survival and is part of the body's overall stress response system.
The sympathetic nervous system originates in the spinal cord and its main function is to activate the physiological changes that occur during the fight-or-flight response.

When urine exits the urinary system, it is at the exterior of the body. There is no system "after" the urinary system.
Response to acute pain is made by the sympathetic nervous system (the nerves responsible for the fight-or-flight response of the body).
