Explanation: 

Detailed explanation-1: -The fight or flight response is an automatic physiological reaction to an event that is perceived as stressful or frightening. The perception of threat activates the sympathetic nervous system and triggers an acute stress response that prepares the body to fight or flee.

Detailed explanation-2: -These hormones cause the sympathetic nervous system to stimulate the pituitary gland and adrenal glands. This triggers the release of catecholamines, including adrenaline, noradrenaline, and cortisol. This chain of reactions results in an increased heart rate, blood pressure, and breathing rate.

Detailed explanation-3: -The responses are usually referred to as the 4Fs – Fight, Flight, Freeze, and Fawn and have evolved as a survival mechanism to help us react quickly to life-threatening situations.

Detailed explanation-4: -There are three stages of fight-or-flight: Alarm, Resistance and Exhaustion, the body’s healthy response to a life-threatening crisis.
