All multicellular organisms have mechanisms for drawing oxygen-rich air (or water) into their bodies and removing carbon dioxide-rich air (or water). A closer look at insect breathing systems makes it easier to appreciate the functions of the more familiar human ventilation system. A detailed study of human ventilation involves the use of a spirometer.
