Lung capacity provides information about the general health of the lungs. MEASURING LUNG CAPACITY. Therefore, the volume of air in the balloon is a representative of the maximum amount of air your lungs can hold up. The air in the lungs is measured in terms of volumes and capacities. This information will be recorded under the "Vital Capacity diameter" column. Make sure to only exhale once into the balloon. 4) Have your partner measure the circumference of the balloon (in cm) using the method your teacher showed you. For example, if your balloon diameter is 14.5 cm, then the corresponding lung volume is 1500 cm3. Pinch the end of the balloon and measure its diameter. Repeat this so that you have 3 total measurements and can take the average and record in the data table. In this activity, you will be measuring the vital capacity and the tidal volume of your own lungs using a balloon (not exactly the most accurate measure, but close enough for our needs). Blow up the balloon several times to stretch it before beginning to take measurements. How much air can you hold in your lungs? Do not force your breathing. Measuring Vital Capacity - Repeat the procedure, only this time inhale as much air as you can and exhale forcefully. Repeat the trials 2 - 3 more times and record.

Stretch a round balloon several times to stretch it out. Exercise 4: Measuring Lung Volumes and Capacities. Materials  -- Balloons, metric ruler, meter stick (or rulers or tape measures), Prediction:   Which factor(s) have the most affect a person’s vital capacity? One way is by using a complex piece of laboratory equipment called a spirometer. It is possible to inhale and exhale more forcefully - the maximum amount of air moved in and out of the lungs is called the VITAL CAPACITY, which is the amount of air a person can expel from the lungs at maximum inhalation. Now breathe out. Consider the difference between internal respiration and external respiration and explain why lung capacity may not have a great effect on length of time you can hold your breath. Blow up the balloon several times to stretch it thoroughly. The amount of air that you move in and out of your lungs while breathing normally is called TIDAL VOLUME. 2. 1. Introduction: Spirometer is an instrument used to measure the lung capacity. Your answer will be in cubic centimeters … Several different lung volume measurements can be made. What about your grandmother versus a child? Can you think of other ways to measure your lung capacity?

Before beginning the experiment, the students will see how the lung works by using a soda bottle as well as a demonstration of the diaphragm. Pinch the end of the balloon and measure its diameter. Place the balloon in your mouth, inhale normally and then exhale normally into the balloon. Human lung size is determined by genetics, gender, and height. After that they will begin the balloon experiment to measure their own lung capacity. 3 0 obj Do not force your breathing. e) Convert the balloon diameters into a measurement of lung capacity by using figure 2. Don't use plagiarized sources. Measuring Lung Capacity Lab. exhale normally into the balloon. How do doctors measure your lung capacity? 3. Be careful with the measurements to be sure you do not flatten the balloon. Follow this number up to the heavy line, then move across to locate the corresponding volume. <>/ExtGState<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> Pinch the end of the balloon and measure its diameter in cm.  Record on data table. Do you think the person with the greatest vital capacity can hold their breath longer than those with a lower vital capacity? Tidal Volume- The amount of air that you move in and out of your lungs while breathing normally (at rest) Vital Capacity- It is possible to inhale and exhale more forcefully - the maximum amount of air moved in and out of the lungs. One way is by using a piece of laboratory equipment called a respirometer or spirometer. Research has shown that the capacity of a person's lungs is proportional to the surface area of his body and his height.   This online calculator will use your height and age to estimate your vital capacity.  Have each of your subjects record their data.
