Step-by-step explanation:
The functions can be attributed to the divisions of the autonomic nervous system as follows:
1. Rest and digest: This function is primarily regulated by the parasympathetic division of the autonomic nervous system. The parasympathetic system promotes relaxation, digestion, and conservation of energy during restful states.
2. Fight or flight: The fight or flight response is primarily regulated by the sympathetic division of the autonomic nervous system. In situations of stress or emergencies, the sympathetic system prepares the body for action by increasing heart rate, dilating blood vessels, and releasing adrenaline.
3. Stress and emergencies: The sympathetic division of the autonomic nervous system is responsible for responding to stress and emergencies. It activates the body's fight or flight response, leading to increased alertness, heightened sensory perception, and mobilization of energy resources.
4. Conservation of energy: The conservation of energy is primarily regulated by the parasympathetic division of the autonomic nervous system. When the body is at rest or during non-stressful situations, the parasympathetic system promotes energy conservation by lowering heart rate, decreasing blood pressure, and stimulating digestion.
