To test yourself with the applet below, first click on one of the labelled lung volume buttons at the bottom.  Then looking at the graph, choose the area which you believe corresponds to that lung volume, and click on the appropriate numbered button.  The number will be replaced with the abbreviation for the lung volume you have chosen.  Complete the test by repeating the above procedure with the remaining buttons.  When you are done, you will be informed of how many you matched correctly.
