Starting off the digestion process. • Students with food allergies should not participate. – Teacher to pass everyone a piece of bread. – Students place bread in mouth (Record taste immediately in journal) – Students allow salvia to moisten bread in mouth and then begin chewing. (Record taste in journal after chewing) Copyright © 2010 Ryan P. Murphy • What happened? • How did the taste change? Why? Copyright © 2010 Ryan P. Murphy • Answer: Bread is a complex carbohydrate (starch). Copyright © 2010 Ryan P. Murphy • Answer: Bread is a complex carbohydrate (starch). The ptyalin in your saliva along with your chewing broke the large sugar molecules into smaller (more sweet) sugar molecules. Copyright © 2010 Ryan P.

Murphy • The GI Tract begins in the mouth where food is broken down mechanically and chemically. The food passes through the pharynx and is moved down the esophagus to the stomach. Acid and movement break the food down further. Chemicals are produced and then released in the liver, gall bladder, and pancreas to the small intestine. Food is broken up further in the intestine and nutrients are absorbed. Water is absorbed in the large intestine and vitamins made. The waste is collects in the rectum until disposal.
