Final answer:
The two functional divisions of the autonomic nervous system are the sympathetic and the parasympathetic divisions. The sympathetic division prepares the body for a "fight-or-flight" response, while the parasympathetic division promotes digestion and relaxation.
Step-by-step explanation:
The two functional divisions of the autonomic nervous system are the sympathetic and the parasympathetic divisions.
The sympathetic division is activated in stressful situations and prepares the body for a "fight-or-flight" response.
The parasympathetic division is active during restful periods and is responsible for conserving energy and promoting digestion and relaxation.
