Human Body: Digestive System
- Briefly introduce the lesson goals and connect to prior knowledge (food components, the importance of nutrients).
- Intro questions: “What is the purpose of the digestive system? What happens to food inside the body?”
Open the 3D model of the digestive system in the Corinth app and visualize together how food travels through the body.
If the model does not load, open it in a new window:

.
| Organ | Function |
|---|---|
| Mouth | Mechanical processing of food, mixing with saliva. |
| Pharynx & Esophagus | Move food to the stomach. |
| Stomach | Mixes food, starts breaking down proteins. |
| Small Intestine | Completes digestion, absorbs nutrients into the blood. |
| Large Intestine | Absorbs water, formation of feces. |
| Rectum | Stores feces until elimination. |
Overview of functions based on the lesson presentation.
| Organ | Function |
|---|---|
| Liver | Produces bile – aids in fat digestion. |
| Gallbladder | Stores and releases bile. |
| Pancreas | Produces digestive juices and hormones (e.g., insulin). |
Summary based on the “Digestive System” presentation.
- Mechanical breakdown of food (mouth, stomach).
- Digestion (enzymes, bile, microorganisms).
- Absorption of nutrients (small intestine – villi) and transport to the blood/liver.
Bullet summary based on the lesson plan.
Try it yourself: Identify the path of food and briefly describe what happens in each section (Mouth → Esophagus → Stomach → Small → Large Intestine → Rectum).
Think about it: Choose two organs – write their function, what you noticed in the 3D model, and what they look like.
Inquiry task: What would happen if the small intestine didn’t function? Why is fiber important? Discuss in pairs or groups.
Today’s mission: Draw the digestive system based on the 3D model and write a short story about how a piece of your favorite food travels through the body.
- Work forms: frontal, individual, in pairs/groups; visualization through 3D model/VR.
- Reflection: What did you enjoy? How did working with the app feel? Advantages of 3D/VR vs. real models.
