Detailed explanation-1: -The autonomic nervous system is a network of nerves that regulates unconscious body processes. The autonomic system is the part of the peripheral nervous system responsible for regulating involuntary body functions, such as heartbeat, blood flow, breathing, and digestion.
Detailed explanation-2: -Heart and circulatory system: The autonomic nervous system regulates how fast and hard your heart pumps and the width of blood vessels. Those abilities are how your autonomic system helps manage your heart rate and blood pressure.
Detailed explanation-3: -Your breathing usually does not require any thought, because it is controlled by the autonomic nervous system, also called the involuntary nervous system. The parasympathetic system slows your breathing rate. It causes your bronchial tubes to narrow and the pulmonary blood vessels to widen.
Detailed explanation-4: -Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The sympathetic nervous system (SNS) releases the hormones (catecholamines-epinephrine and norepinephrine) to accelerate the heart rate.
