What does the output of the ANS control?

The output of the autonomic nervous system (ANS) controls involuntary physiological functions, such as heart rate, digestion, respiratory rate, and reflexes. It regulates the body's homeostasis, responding to stress through the sympathetic division (fight or flight response) and promoting relaxation and recovery through the parasympathetic division (rest and digest). Overall, the ANS ensures the body's internal environment remains stable despite external changes.
