Fight or Flight

The fight or flight response is a biochemical reaction in animals that enables them to rapidly produce sufficient energy to flee or fight in a threatening situation.

## Notes - The fight or flight response is a biochemical reaction in animals that enables them to rapidly produce sufficient energy to flee or fight in a threatening situation. - Walter Cannon discovered this biological reaction. - When presented with an immediate stressor, the body releases [adrenaline](/zettel/adrenaline), [noradrenaline](/zettel/noradrenaline), and [cortisol](/zettel/cortisol). As a result, the heart rate increases, and blood is directed away from the organs and toward the arms and legs to fight or flee. - The body spends less energy on functions such as thought, which can prejudice [short-term memory](/zettel/short-term-memory) formation. ## References - [GoodTherapy.
