In this video, middle school students will learn all about their lungs, how they work, and the main purpose of the respiratory system.

We’ll break down the important roles of the diaphragm, nose, mouth, pharynx, larynx, trachea, rib cage, and more! Explore how the alveoli help exchange oxygen and carbon dioxide, and check out some fun facts along the way. Plus, we’ll include turn-and-talk moments for interactive learning!
