Key Questions


  • The author says by the time your food reaches your stomach, it is unrecognizable. What does it mean if something is unrecognizable? Why is the food unrecognizable?
  • Describe the surface of the tongue. Why is it that way?
  • What does the author teach about digestion in the section "Mouth Watering"?
  • What is swallowing? What does it mean that swallowing is a reflex action?
  • Why do stomachs have a stretchy wall? What happens in the stomach?
  • What is the esophagus? Why is it important?
  • How do the illustrations and diagrams on pp. 86-87 help a reader better understand the different parts of digestion?









There is not a lot of text on this day. The key is for students to really be able to explain the cause and effect between different steps of the digestive process.
