Verified step by step guidance

1. Understand the role of the parasympathetic division: It is part of the autonomic nervous system, which controls involuntary bodily functions.
2. Recognize the primary function of the parasympathetic division: It is responsible for the 'rest and digest' response, which conserves energy and promotes maintenance activities.
3. Identify the neurotransmitter used by the parasympathetic division: It primarily uses acetylcholine, not norepinephrine, which is used by the sympathetic division.
4. Differentiate between the parasympathetic and sympathetic divisions: The sympathetic division prepares the body for 'fight or flight' situations, increasing heart rate and blood pressure, while the parasympathetic division does the opposite.
5. Conclude that the statement 'It is responsible for the 'rest and digest' response' correctly applies to the parasympathetic division, as it promotes relaxation and energy conservation.
