The body's involuntary functions are regulated by which nervous system?

• A. Central
• B. Somatic
• C. Peripheral
• D. Autonomic

Answer: (D)

Autonomic nervous system controls involuntary bodily functions that happen without conscious input, such as heart rate, digestion, breathing, pupil size, and glandular activity. It adjusts these processes automatically through its sympathetic and parasympathetic divisions to respond to stress, rest, and everyday needs. The central nervous system (brain and spinal cord) processes and integrates information, the somatic system governs voluntary muscle movements, and the autonomic system is the specific pathway that manages automatic regulation of organs and bodily functions.
