Autonomic control system

The autonomic control system is part of the peripheral nervous system, and has the important function of maintaining the internal environment of the human body in a steady condition.

As various changes occur to the body both internal and external this control system reacts by regulating such things as the blood pressure, heart rate and salts in the blood stream and so on.

The autonomic control system, as the name implies, generally works automatically without voluntary control, as we do not consciously direct our rate of breathing or heart beating.
