In contrast to the voluntary nervous system, the "involuntary" or autonomic nervous system is responsible for homeostasis, maintaining a relatively constant internal environment by controlling such involuntary functions as digestion, respiration, perspiration, and metabolism, and by modulating blood pressure. Although these functions are generally outside of voluntary control, they are not outside our awareness, and they may be influenced by one's state of mind.
The autonomic nervous system (ANS) is the part of the nervous system of the higher life forms that is not consciously controlled. It is commonly divided into two usually antagonistic subsystems: the sympathetic and parasympathetic nervous system, and involves the homeostasis of organs and physiological functions.
Autonomic nervous system is the part of the nervous system that controls unconscious systemic functions, such as respiration and beating of the heart. The autonomic nervous system is divided into two; the sympathetic and the parasympathetic nervous system. These two systems govern are responsible for opposing signals. A sympathetic signal ("fight or flight") will speed the heart rate and strength of contraction. A parasympathetic signal slows the heart rate. In this way, the autonomic nervous system regulates the blood pressure.

The autonomic nervous system (ANS) (or visceral nervous system) is the part of the peripheral nervous system that controls homeostasis or the constancy of the « milieu intérieur » (the content of tissues in gasses, ions and nutrients). It does so mostly by controlling cardiovascular, digestive and respiratory functions. Salivation, perspiration, diameter of the pupils, micturition - (the discharge of urine), and erection are also controlled by the ANS.
