Answer:
On instinct, animals and humans react to threats with a general discharge of the sympathetic nervous system. Adrenaline pumps through the body in the face of fear, and we instinctively have what’s called, a fight or flight response, described by Walter Cannon in the 1920s, in which we decide to run away from harm, or stand and fight. Physically, the amygdala (which is the part of the brain responsible for emotions, survival tactics, and memory) is activated and sends signals to the frontal cortex, which is responsible for analyzing and interpreting data. Then the brain evaluates the threat, sparking the primitive response to flee (avoid) or fight.
Explanation:
Basically, fear helps us survive and triggers the fight or flight response.
