Did You Know….
……that when you cough the stream of air liaving your lungs can reach a speed of 160 kilometres per hour?
……that your lungs have a surface area of 70 square metres – about 40 times the area of your skin?
……that you take about 20,000 breaths every day?
Globus and his friends lead you into the extraordinary world of the lungs. The lungs get rid of the waste gas, carbon dioxide, and refresh themselves with life – giving oxygen. You will find out how that happens and what parts of your body are used when you breathe in this volume of How My Body Works.
