Carson is taking a flight to meet his girlfriend for a long-awaited vacation. The plane hits a pocket of unexpected but rough turbulence, causing the plane to veer sharply to the left. Explain how the biological system of fight-or-flight will prepare
Carson to respond to the situation.
What will be an ideal response?
Experiencing fear for his safety, Carson’s sympathetic division of the autonomic nervous system (ANS) will trigger a cascade of adrenaline from the adrenal medulla, which will in turn cause Carson’s pupils to dilate, decrease salivation, increase perspiration and respiration, increase his heart rate, and inhibit digestion. These responses will help Carson protect himself as much as possible in the event of continued turbulence. After the plane passes through the turbulence and the flight stabilizes, Carson’s parasympathetic system will recognize the threat is over, and therefore the adrenal glands will stop producing adrenaline, his heart rate and breathing will slow down, his perspiration will decrease, his pupils will contract, and his digestion will resume.
