Chapter 12 Autonomic Nervous System
The automatic nervous system is the part of our body that takes care of functions we don’t deal with directly, such as breathing, the beating of the heart and the digestion of food. What do you know about this extremely crucial system, find out in this quiz on Chapter 12 Autonomic Nervous System.
