Respiratory System Working Model

Want to know how your body breathes every moment of the day? This activity helps you explore how the respiratory system works and why breathing is so important for staying alive and healthy. You’ll learn how air travels through your body and helps you get the oxygen you need.

As you observe the working model, you begin to understand how the lungs, air passages, and breathing movement work together. Watching the system in action builds your observation and problem-solving skills while helping you think scientifically about how body systems function.

You’ll strengthen your science knowledge by learning new words related to breathing and human health. Reading short explanations and connecting them to what you see makes learning clearer and easier to remember. This activity helps you link everyday breathing to important science concepts.
