Question

why adrenaline known as Flight and Fight hormone( proper reason)

Answer 1

Adrenaline is the body's activator, and is released in response to anxiety, exercise, or fear. This is the basis of the so-called 'fight-or-flight' reaction. ... Fright causes the brain to send signals to the renal glands which start pumping large amounts of adrenalininto the bloodstream.

Answer 2

It is a physiological reaction that occurs in animals in response to a detected dangerous event, attack, or survival threat. This was first described by American physiologist Walter Bradford Cannon. In his theory, he stated that animals react to threats with a discharge coming from the sympathetic nervous system, preparing the animal for fleeing or fighting.
