Answer:
Parasympathetic nervous system
Step-by-step explanation:
The parasympathetic nervous system becomes active when the person is relaxed and resting. During these conditions, the parasympathetic nervous system becomes activated to restore the energy of the body. The function of this system is to promote the digestion and absorption of the nutrients to increase the stored fuel of cells. It activates the digestive glands to secrete the digestive juice and also slows down the responses activated by the sympathetic nervous system during emergency conditions.
