One way, is by using a piece of laboratory equipment called a spirometer. Lung Capacity Lab You will complete a lab that mixes a virtual component with a hands-on component. Hold the straw in place using the blu-tack (or other modelling material) to create a lid. This will make it easier for you to blow up your balloon during the experiment by removing some of the resistance. #archive:hover { zoom:101%;) Materials • Balloon • 2 rulers Procedure A: Vital Capacity 1. As we breathe out the diaphragm raises again. (To report any malicious content send the URL to oocities(at gmail dot com). In this lab, you will measure three indices of lung capacity using a balloon. Lung volume is expressed in cubic centimetre units (cm3). 2. Measuring Lung Capacity Background: The amount of air that you move in and out of your lungs while breathing normally is referred to as TIDAL VOLUME. LAB: LUNG CAPACITY. The amount of air taken in or expelled during normal breathing is about 500 cm3. <>/ExtGState<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> the data on your lab partner. 2 0 obj The expiratory reserve is the amount of air that remains in the lungs after a normal exhalation. When the bottle is sealed off by the balloon on one end and the cap, straw, and balloon at the other, you create a container that is nearly airtight. How Does It Work? Then, blow up and deflate your balloon several times. d.write('
