The sympathetic nervous system the part of the nervous system that deals with heart rate, blood pressure, and how your blood vessels constrict.The sympathetic nervous system is located in your spinal cord. This part of the nervous system is also know as your fight or flight response. What the fight or flight response is is your body’s defense system with it senses fear. You feel this way because there is a sudden hormone which is activating your bodies sympathetic nervous system.
This fight or flight response can happen to anybody at anytime that they fell as if they are in danger. One time when I was younger we use to go to livestock shows all over the east coast so we had to get up early in the mornings to do barn work. And it was usually pitch black out and one time I was walking into to one of our barns and I though I heard a noise coming from the dark shadows. When I heard this noise my body froze, heart started to beat faster cause I had no idea what was out there that I couldn’t see. The only thing that I could think to do was to run into the barn and turn on the lights so I could figure out. This was an example of the flight part of the sympathetic nervous system because it was telling me to get out of there because what was making that noise could potentially hurt me.
After I ran into the barn and turned on the light I realized that there was nothing out there that could harm me. Once realizing that my heart rate went back down and I was no longer scared of what could be out there. I believe that this is a good example of the body’s natural protection. My experience shows how the body uses its natural functions to help protect us from danger.
