    The Autonomic Nervous System:

    The autonomic nervous system (ANS) is the part of the nervous system that regulates normal bodily functions including digestion, the heart and respiratory rates, and the activity of numerous other organs. It is comprised of two further subdivisions: the sympathetic and the parasympathetic nervous systems.
