Detailed explanation-1: -The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.
Detailed explanation-2: -The autonomic nervous system controls all “automatic” body functions, such as breathing, heart rate, blood pressure, sweating, mouth-watering (salivating), and the movement of food through the intestines (peristalsis).
Detailed explanation-3: -The Brain. The brain processes most of the body’s sensory information and is responsible for coordinating conscious and unconscious body functions including feeling, thinking, and maintaining homeostasis, which is the body’s ability to maintain a stable environment.
