Which of these physiological changes would not be considered part of the sympathetic fight-or-flight response?
- A. increased heart rate
- B. increased sweating
- C. dilated pupils
- D. increased stomach motility
Correct Answer: D
Rationale: The correct answer is D: increased stomach motility. In the sympathetic fight-or-flight response, the body prioritizes blood flow to essential organs and muscles, leading to decreased activity in non-essential functions like digestion (stomach motility). This is to conserve energy for immediate action. Increased heart rate, sweating, and dilated pupils are all part of the fight-or-flight response as they prepare the body for quick action and heightened awareness.
