You are doing so good!  
There are only a couple stops left.


Continuing on our journey, we travel to the system
that is made up of the brain, spinal cord, and nerves.  It has
three parts: the central system, the peripheral system, and the
autonomic system.  These three parts control your
senses, nerve impulses, heartbeat, and digestion.  
Can you name this system?





a. Endocrine System

b. Nervous System

c. Immune System
