Editing Fight-or-flight response (section)

===Function of physiological changes===
The physiological changes that occur during the fight or flight response are activated to give the body increased strength and speed in anticipation of fighting or running. Some of the specific physiological changes and their functions include:<ref name="Physiological Changes - Tripod2">{{cite web |last=Stress Management for Health Course |title=The Fight Flight Response |url=http://stresscourse.tripod.com/id11.html |access-date=19 April 2013}}</ref><ref name="The Science of Stress - Olpin2">{{cite web |last=Olpin |first=Michael |title=The Science of Stress |url=http://faculty.weber.edu/molpin/healthclasses/1110/bookchapters/stressphysiologychapter.htm |url-status=dead |archive-url=https://web.archive.org/web/20171120215838/http://faculty.weber.edu/molpin/healthclasses/1110/bookchapters/stressphysiologychapter.htm |archive-date=2017-11-20 |access-date=2013-04-25 |publisher=Weber State University}}</ref><ref name=":23">{{Cite book |last1=Myers |first1=David G. |title=Psychology |last2=DeWall |first2=C.

* Increased [[blood flow]] to the muscles activated by diverting blood flow from other parts of the body to make taking quick action easier.
* Increased blood pressure and heart rate enhance cardiac output in order to supply the body with more energy.
* The [[liver]] secretes increased amounts of [[glucose]] (through adrenaline-induced [[glycogenolysis]])<ref>{{Cite web |title=Glycogenolysis {{!}} Glucose Metabolism, Liver Function & Regulation {{!}} Britannica |url=https://www.britannica.com/science/glycogenolysis |access-date=2025-01-09 |website=www.britannica.com |language=en}}</ref> and fats into the blood to provide the body with a fuel source to meet energy demands.
* The [[respiratory rate]] increases to supply the oxygen necessary to help burn the extra glucose.
* The [[Coagulation|blood clotting]] function of the body speeds up in order to reduce [[bleeding]] and prevent excessive blood loss in the event of an injury sustained during the response.
* Increased [[Muscle tone|muscle tension]] in order to provide the body with extra speed and strength, which can result in trembling or shaking until the tension is released.
* The pupils [[Mydriasis|dilate]] to let in more light, allowing for better vision of the body's surroundings.
