Which is the true of the automatic nervous system?

The autonomic nervous system is responsible for regulating involuntary bodily functions, such as heart rate, digestion, respiratory rate, and blood pressure. It is divided into two branches: the sympathetic nervous system, which is responsible for the "fight or flight" response, and the parasympathetic nervous system, which is responsible for the "rest and digest" response. The autonomic nervous system works automatically and unconsciously to maintain homeostasis in the body.
