Which of the following best describes the function of the sympathetic nervous system?
DiKsa [7]

Answer;

B. It arouses the body and expends energy.

Explanation;

-The autonomic nervous system controls the insides of the body: the viscera or gut. It carries information about the inside of the body to the CNS and controls the action of internal organs. The autonomic nervous system has two divisions: the sympathetic division and the parasympathetic division.

-The sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. The parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
