Answer to Question 1

A
The sympathetic nervous system gears up the body for fight or flight situations with epi-nephrine that will raise the blood pressure (BP), reduce bowel motility, and energize the whole body to defend itself in a stressful situation. The parasympathetic system slows the heart rate af-ter stress, supports deep sleep, and relaxes blood vessels.
