PATHOLOGY

Detailed explanation-1: -The “fight or flight” reaction makes our breathing shallow and rapid to increase oxygen, making our bodies ready for action. If we do not use this extra oxygen by running or fighting, there is temporarily an imbalance in the amount of oxygen and carbon dioxide in our blood.

Detailed explanation-2: -Stress triggers your adrenal glands to release cortisol and adrenaline, which can lead to an increased respiratory rate, and make it especially hard for people with underlying lung problems (like asthma, COPD) to breathe.

Detailed explanation-3: -Specifically, fight-or-flight is an active defense response where you fight or flee. Your heart rate gets faster, which increases oxygen flow to your major muscles. Your pain perception drops, and your hearing sharpens. These changes help you act appropriately and rapidly.
