Home | Parts of System | Functions | Bibliography
The web sites I used were very many.  To find most of my information I used google and Yahoo . com.  I also used discoverykids.com.  One of the others was bigmamashealth. com.  These were the sites that helped me the most.  These give you information on all the parts of the system.  They helped me alot so I hope they help you to.  The books I used were the Human Body Books and The Digestive System.  I know I was not very specifis but I hope you will forgive me.
