The Nervous and Digestive System
1. The main parts of the Nervous System are the brain, spinal cord, nerves, and sense organs.
2. The job of the Nervous System is to control all body systems.
3. The brain is the control center of the nervous system.
4. The brain uses information it gets from your body to direct how each body system works.
5. The brain and all other parts of the nervous system are made up of nerve cells, or neurons.
6. Groups of neurons are called nerves and they pass along information.
7. Your spinal cord is a tube of nerves that runs through your spine, or backbone.
8. When a person swings a bat, the muscles receive a message from the brain to swing the arms.
9. The main parts of the digestive system is the mouth, esophagus, stomach and intestine.
10. The job of the digestive system is to provide nutrients to the body.
11. Digestion begins in the mouth when you grind up food with your teeth.
12. Saliva softens the food.
13. After you swallow, the food enters your esophagus which connects your mouth with your stomach.
14. The stomach muscles squeeze the food and mix it with digestive juices.
15. The food is then passed on into the small intestine where the nutrients pass through the walls into the blood. The blood carries the nutrients to the body’s cells.
16. Lastly, the food reaches the large intestine and is then passed through the body.
17. Fiber helps your digestive system work well. Eat foods with fiber, such as fresh vegetables, beans, fruits, cereals, and breads.
