The autonomic system is indeed responsible for sustaining life processes by transmitting information to and from internal organs. This division of the nervous system controls involuntary bodily functions, which include regulating heart rate, digestion, respiratory rate, and more. It operates without conscious control, allowing the body to maintain homeostasis and respond automatically to changes in the environment.

The autonomic system itself is divided into two main branches: the sympathetic and parasympathetic systems. The sympathetic system prepares the body for stressful situations, often referred to as the 'fight or flight' response, while the parasympathetic system conserves energy and promotes 'rest and digest' functions. This balance is crucial for the body to function efficiently.

Understanding the autonomic system's role highlights its significance in managing bodily functions that keep us alive and healthy, making it integral to our overall biology.
