How Does Your Body Work Your Respiratory System Judith Jango-Cohen a Lerner Publications Company Minneapolis
Chapter 1 THE NEED TO BREATHE Imagine that you are sleeping Your chest floats up and down Quietly your breath flows in and out You breathe slowly when you are asleep How do you breathe when you run fast 4
Next imagine that you are running a race Your mouth sucks in air Your nostrils stretch wide At the finish line you drop onto the grass As you gasp for breath your chest pumps up and down You breathe faster when you run than when you rest 5
