Question

select the correct answer from each drop-down menu. alma is walking in a park. suddenly, a wild dog charges toward her. alma is frightened. the sympathetic nervous system starts to respond by increasing her heart rate and dilating her pupils. after running for a few minutes, alma realizes that the dog has fallen far behind. at this point, her dropdown starts working to relax her body by slowing down her heart rate and constricting her pupils.

Explanation:

The sympathetic nervous system is responsible for the "fight - or - flight" response (increasing heart rate, dilating pupils). When the threat passes, the parasympathetic nervous system is responsible for the "rest - and - digest" response, which relaxes the body by slowing the heart rate and constricting pupils. The somatic nervous system is mainly for voluntary muscle control, so it's not relevant here.

Answer:

parasympathetic nervous system
