Quizplus · Accepted Answer

Increased heart rate, blood pressure, bronchodilation, diaphoresis, and pupillary dilation are all physiological responses mediated by activation of the adrenergic receptors in the sympathetic nervous system. Adrenergic receptors are stimulated by the release of catecholamines (e.g., epinephrine and norepinephrine) during the fight or flight response, leading to these responses. Anticholinergic effect (B) would have opposite effects, such as decreased heart rate and bronchoconstriction. Vagomimetic activity (C) refers to stimulation of the parasympathetic nervous system, which would have similar effects as anticholinergic drugs. Alpha1 blockade (D) would lead to vasodilation and decreased blood pressure.
