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, noradrenaline, and 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 formation.
