What is the purpose of the fight or flight response?

Answer 1

Most of the adrenaline in the human body is released by the adrenal gland. The adrenal gland is a part of the sympathetic nervous system, a branch of the nervous system that regulates the classic stress response and has numerous roles in other normal body functions. Adrenaline, called epinephrine by scientists in the US, is the major hormone released during the classic stress response (also called the fight-or-flight response), which is why it is often considered a fight-or-flight hormone. It has several actions in the body that make it good at this job: it dilates the pupils to increase the amount of light that enters the eyes, it causes sweating to help dissipate heat, it increases blood flow to the muscles, it increases the heart rate and force of contraction, and it makes glucose available in the blood for use by other organs.

Answer 2

During the fight-or-flight response, your body provides you with energy, reflexes, and strength you may need to respond to the stressor. As past of the fight-or-flight response, your body releses epinephrine formerly called andrealine, is one of the hormones that are released by the body in times of stress. Epinephrine prepares the body for quick action by triggering the changes listed below.

• Your breathing speeds up, which helps get more oxygen throughout your body.
• Your heart beats faster, which increases the flow of blood to carry more oxygen to your muscles.
• Your muscles tense up, which prepares you to move quickly.
• the pupils of your eyes get wider, which allows extra light for more sensitive vision.
• Your digestion slows down, because digestion is an unneccssary activity during an emergency.
• Blood sugar increases to provide more fuel for fighting or running.

Answer 3

This fundamental physiologic response forms the foundation of modern day stress medicine. The "fight or flight response" is our body's primitive, automatic, inborn response that prepares the body to "fight" or "flee" from perceived attack, harm or threat to our survival.

Answer 4

Adrenaline is the hormone that is normally release when a person is scared. It speeds up your heart rate and dilates your veins so that you are at maximum blood flow and your muscles can get the maximum energy possible as fast as possible. It is design so that in dangerous situations you either have maximum strength for a fight, or you have maximum energy to run as fast and as far as your body can.
