Answer:
parasympathetic nervous system
Explanation:
After the fight or flight response generated by the sympathetic division under stress conditions, parasympathetic division triggers rest and digest activities to conserve and restore the energy levels of the body during the recovery time. It includes the stimulation of digestive glands and smooth muscles of the digestive tract to trigger the digestion and absorption of nutrients.
The parasympathetic division also slows down the physical activities of the body. It decreases heart rate, triggers constriction of airways and reduces the diameter of the pupil. Therefore, the parasympathetic division restored Malcolm to the normal state after the given stress condition.
