An ideal tool for educating pediatric patients, this chart describes why we breathe and illustrates the respiratory system and the role of important organs such as the brain, nose, trachea, lungs, heart, and diaphragm. It shows what happens inside the lungs and the flow of air during the breathing process and shows smoke-damaged alveoli. The chart includes fun facts ("You take over 20,000 breaths a day!"), how to make a model of your lungs, and answers to questions like "Why do I yawn?" and "How do I laugh?" Bright colors, bold figures, and appealing, anatomically correct illustrations make learning enjoyable.
