The respiratory system takes air into the lungs. It puts oxygen into the blood and takes the carbon dioxide out of the blood and exhales it. The major organs in the respiratory system are the lungs, trachea, bronchioles, mouth, nose and epiglottis.



We found this picture in the book The Lungs and Breathing, by Bryan R. Ward, (1982).


The respiratory system is like a bike pump because when you push the handle on the bike pump down the tire fills up with air like your lungs fill up with air.
