The Digestive System

All About Your Digestive System – Its Parts and Functions
Note from Mrs. G. This site,  http://easyscienceforkids.com, looks like it is for younger students.  Don't worry about that as there is some very good information here, including the graphic below.
Your body starts getting ready for digestion as soon as you smell the food. When you take a bite of your favorite food, saliva mixes with it to make it soft. The food is pushed along through the esophagus to your stomach. Acids and juices in your stomach break it down more. The liver and intestines pull out nutrients that your body needs, and the food goes on its way. Other organs also help you digest your food.

Digestive System
If we feel hungry, we eat and then go about our business. Few of us realize that as long as 20 hours after we eat that pizza or hot dog our body is still working to turn the usable portion into energy and discard the rest. This site explains that process in a detailed but easy to understand way. The site covers the path food takes from the time it enters the body, digestive disorders, and includes a diagram that represents how food travels through the esophagus and intestines. The diagram requires Micromedia Flash to view.

"Why is digestion important?

Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body. The body breaks down nutrients from food and drink into carbohydrates, protein, fats, and vitamins."
