Once upon a time, there was a little girl named Lily who lived inside the human body. She was in charge of making sure everything worked correctly. One day, she noticed that her friend, the stomach, was having trouble rotating the food that came from the mouth. The food wasn't breaking down into smaller pieces so it could be sent to other parts of the body for energy.

Lily knew that the digestive system was responsible for breaking down food, but she also knew that the circulatory system and the nervous system needed to work together with the digestive system to help it properly.

So, she called a meeting with all the systems in the body to find a solution. They decided that they needed to help the stomach by sending more carbon dioxide to it. The stomach could use this carbon dioxide to help break down the food.

Lily and the other systems worked together to make sure the stomach received enough carbon dioxide. And, just like magic, the food started breaking down into smaller pieces and the stomach could rotate it properly.

The body was happy and healthy again, thanks to Lily and the teamwork of all the systems. The end.

Reflections

1. What was the problem with the stomach?
2. How did Lily and the other systems solve the problem?
3. Why was the teamwork of the digestive, circulatory, and nervous systems important for the body's health?
4. Can you think of a real-life example of teamwork solving a problem?
