Intro to The Nervous System
The nervous system is perhaps the most important system in the body.The most impotant parts are the brain,spinal cord, nerves, and neurons. The nervous system is made up of the Cns(central nervous system) and the PNS(peripheral nervous system).The nervous system works together with all of the other systems including the digestive system, the respiritory system, and the immune system. Without the nervous system, none of the other systems would be able to function. The brain tells all of the systems what to do. The brain tells the digestive system when it needs nutrients and it also tells the immune system when to prepare to defend the body against diseases. Lets explore the nervous system!
