Question

Quizplus · Accepted Answer

Rusty's digestion would not be enhanced in this situation as his body would be preparing for a fight or flight response, which would divert blood flow away from the digestive system. Therefore, statement B is not true. The other statements are all possible physiological responses to a perceived threat or challenge. A) Rusty's heartbeat would be accelerated as part of the fight or flight response. C) Rusty's pupils would be dilated to allow more light in and improve his vision during the potential fight. D) Rusty experiencing piloerection (raised hackles) is also possible as it is a sign of arousal or aggression.
