Which division of the autonomic nervous system is responsible for automatic bodily functions such as heart rate and digestion?

Automatic bodily functions like heart rate and digestion are controlled by the autonomic nervous system, which handles activities that run largely without our conscious input. This system keeps body processes running smoothly by constantly adjusting organs and glands to maintain balance. Within it, the sympathetic division ramps things up for action (increasing heart rate, redirecting energy), while the parasympathetic division promotes rest and digestion (slowing the heart and stimulating digestive activity). The other options don’t fit because the somatic nervous system governs voluntary muscle movements, the central nervous system is the brain and spinal cord that process information (not the automatic control itself), and the peripheral nervous system includes all nerves outside the CNS but doesn’t specify the automatic regulation of internal organs—that job belongs to the autonomic component.
