Digestive System Model Making Link - https://youtu.be/IewP64hes0g

In this video, we show how to make a human digestive system working model step by step using:

LED lights to represent different digestive organs
Switches to control each organ’s function

When each switch is turned ON, the respective organ (mouth, esophagus, stomach, small intestine, large intestine) lights up, making it easy to understand the process of digestion.

Concept Explanation:
Food enters through the mouth, passes the esophagus, gets digested in the stomach, nutrients absorbed in the small intestine, and waste excreted via the large intestine. LEDs make the process interactive and fun!
