Final answer:
The autonomic nervous system has two divisions: the sympathetic division and parasympathetic division. The sympathetic division activates the fight-or-flight response, while the parasympathetic division controls routine functions.
Step-by-step explanation:
The autonomic nervous system (ANS) has two divisions called the sympathetic division and parasympathetic division. Both divisions of the ANS affect the same organs and glands, but they generally do so in opposite ways. The sympathetic division activates the body's fight-or-flight response during emergencies, while the parasympathetic division controls routine functions of the body at other times.
