Question

Quizplus · Accepted Answer

Sympathetic innervation primarily prepares the body for "fight or flight" responses, which includes diverting blood away from the gastrointestinal (GI) tract to more critical muscles and organs. This is achieved through vasoconstriction of blood vessels to the GI tract. The other options (A, C, D, E) are more closely associated with parasympathetic innervation, which promotes rest-and-digest activities, including stimulating digestive activity, gland secretions, peristalsis, and relaxing GI sphincters.
