The automatic nervous system controls involuntary or automatic functions. There are two subsystems of the automatic system. Which one is responsible for decreasing the processes of digestion and elimination?
  1. The sympathetic nervous system
  2. The somatic nervous system
  3. The parasympathetic nervous system
  4. The central nervous system
Explanation
Answer: A - The sympathetic nervous system is responsible for decreasing the processes of digestion and elimination. It is also known as the “fight or flight” system; it is the system that takes over during times of stress. It releases hormones that also increase heart rate, respiration, and blood pressure. The parasympathetic nervous system complements the sympathetic nervous system-it takes over in times of relaxation and performs in an opposite manner.
