The nurse is teaching a group of 6-year-olds about the digestive system. Which statements by the children indicate that teaching has been effective?
Select all that apply.
1. "Grown-ups have 28 teeth."
2. "Spit helps you taste your food."
3. "Food starts breaking down in the stomach."
4. "It's like a tube. Food I need goes in one end. What I don't need comes out the other."
5. "The food moves through the tube in waves, like a snake eating a mouse."
Correct Answer: 2, 4, 5
Saliva begins the process of breaking down food and does help one taste food; the GI tract is like a tube in which food enters one end and waste products exit the other end; and food is propelled through the tube in peristaltic waves, which a child might equate to the motion of a snake eating a mouse. Adults have 32 teeth, and food begins to digest in the mouth due to the action of enzymes such as amylase.
