MICROANATOMY

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: -Some of the physical signs that may indicate that the fight-or-flight response has kicked in include: Rapid Heart Beat and Breathing: The body increases heartbeat and respiration rate in order to provide the energy and oxygen to the body that will be needed to fuel a rapid response to the danger.

Detailed explanation-3: -Your sympathetic nervous system is a network of nerves that helps your body activate its “fight-or-flight” response. This system’s activity increases when you’re stressed, in danger or physically active.

Detailed explanation-4: -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-5: -During the classic “fight-or-flight” stress response, sympathetic nervous system activation leads to catecholamine release, which increases heart rate and contractility, resulting in enhanced cardiac output.
