📐 Labelled Diagram of Human Digestive System for Class 7

The digestive system breaks food down into nutrients the body can absorb and use for energy. This model traces the journey from mouth to intestines, labelling each organ along the way.

Why It's Important

• Breaks food down into usable nutrients
• Absorbs nutrients the body needs to grow and repair
• Removes what the body can't use as waste
• Supplies the energy for every body process

Observation Points

• Trace the pathway from mouth to stomach to intestines
• Notice the length and coiling of the small intestine
• Compare the small and large intestine's width
• Identify where most nutrient absorption happens

Learning Objectives

• Identify the main organs of the digestive system
• Explain what happens to food at each stage
• Describe where most nutrients are absorbed
• Understand how long digestion takes

Summary

The digestive system breaks food down step by step -- from chewing in the mouth to absorption in the intestines -- extracting the nutrients the body needs to function.
