Level#1: The digestive system includes many organs. These organs include the mouth, esophagus, stomach, and small intestine. They are all connected, and form one long tube called the digestive tract. Digestion begins in the mouth with chewing the food. As you chew, a liquid called saliva is released. Saliva wets the food and helps you to swallow it.

2. What do these connected organs form?
3. Where and how does digestion begin?
4. What is the name of the liquid released when we chew and how does it help us?

Level#2: The digestive system includes many organs. These organs include the mouth, esophagus, stomach, and small intestine. They are all connected, and form one long tube called the digestive tract. Digestion begins in the mouth with chewing the food. This is a form of mechanical digestion. As you chew, a liquid called saliva is released. Saliva wets the food and helps you to swallow it. Saliva also has an enzyme that breaks down starch into sugar. This is a form of chemical digestion. The esophagus connects the mouth to the stomach. Muscles in the esophagus squeeze together, pushing the food down to the stomach. The epiglottis is a flap of tissue that closes when you swallow. It keeps the food from going down the windpipe.

Level#3: The digestive system includes many organs. These organs include the mouth, esophagus, stomach, and small intestine. They are all connected, and form one long tube called the digestive tract. Digestion begins in the mouth with chewing the food. This is a form of mechanical digestion. As you chew, a liquid called saliva is released. Saliva wets the food and helps you to swallow it. Saliva also has an enzyme that breaks down starch into sugar. This is a form of chemical digestion. The esophagus connects the mouth to the stomach. Muscles in the esophagus squeeze together, pushing the food down to the stomach. The epiglottis is a flap of tissue that closes when you swallow. It keeps the food from going down the windpipe. Food passes from the esophagus into the stomach. It can be stored there for up to six hours. Both mechanical and chemical digestion take place in the stomach. Muscles in the stomach move the food around. Enzymes and acids are released to break down the food chemically. When the food leaves the stomach it is mostly liquid. The liquid goes into the small intestine in which most digestion takes place.
