Vedclass · Answer

(B) The sympathetic nervous system prepares the body for 'fight or flight' responses,which includes dilating the pupils,increasing heart rate,and inhibiting intestinal motility.In contrast,the parasympathetic nervous system promotes 'rest and digest' activities,which includes constricting the pupils,decreasing heart rate,and stimulating intestinal motility.Comparing the given options:Option $A$ is incorrect because the sympathetic system inhibits salivary secretion,while the parasympathetic system stimulates it.Option $B$ is correct because the sympathetic nervous system causes pupil dilation,and the parasympathetic nervous system causes pupil constriction.Option $C$ is incorrect because the sympathetic system increases heart rate,while the parasympathetic system decreases it.Option $D$ is incorrect because the sympathetic system inhibits intestinal motility,while the parasympathetic system stimulates it.
