A) Decreased salivary gland production
B) Vasodilation
C) Increased peristalsis
D) Bronchodilation
E) Pupillary constriction
Ans: B, C, E
Feedback:
Stimulation of the parasympathetic nervous system results in the opposite reactions to those triggered by the adrenergic system: blood vessels dilate, sending blood to the gastrointestinal (GI) tract; secretions and peristalsis are activated and salivary glands increase production; the heart slows and pulmonary bronchioles constrict; the smooth muscle of the bladder contracts; and the pupils of the eyes constrict.
