Beakman's World: How the Lungs Work
00:02:05 - 00:06:25
Human Anatomy → Lungs → How the Lungs Work
Beakman explains why we breathe and then uses an anatomical model to show which parts of the lungs were involved. He uses a balloon model and a jar to demonstrate how the diaphragm works and then an animated clip to show how oxygen gets into the blood and goes to the cells.
