The fight or flight response is a physical response; a strong stimulus or emergency causes the release of a chemical called nor-adrenaline (also called norepinephrine)
The sympathetic nervous system originates in the spinal cord and its main function is to activate the physiological changes that occur during the fight-or-flight response.
Indigestion often accompanies an emotional upset, because the part of the nervous system involved in the so-called "fight-or-flight" response also affects the digestive tract. People diagnosed with anxiety or somatoform disorders frequently.
No, it slows so you can conserve your energy.
The fight or flight response is the hormone adrenaline so the chances are that at least some of your senses become more alert.
Yep! The sympathetic nervous system causes both vasoconstriction & vasodilation. During "fight or flight" you need more O2/blood delivered to your skeletal muscles. The SNS causes vasodilation in skeletal muscles. The other organs, of the body (like digestive organs) are not needed for "fight or flight" survival. The SNS causes vasoconstriction in these organs.
