In this TedEd video, shared in November 2014, watch an informative animation by Emma Bryce about how our lungs work.
Breathing occurs 15-25 times a minute, and the average person will inhale 10,000 liters of air each day. Sound simple? It isn’t. The act of breathing is incredibly complex and requires the brain, lungs, heart and diaphragm to work in harmony with each other in order to deliver oxygen-rich blood to the entire body.
All of this happens without most of us even thinking about it — unless we suffer from a lung disease that makes breathing difficult, like cystic fibrosis.
