Hold the end of the balloon shut to stop the air from escaping. Vital Capacity is the maximum air moved in and out of the lungs. var width = window.innerWidth || (window.document.documentElement.clientWidth || window.document.body.clientWidth); This amount of air provides enough oxygen for the body when the person is resting. Measuring Lung Capacity Pre-Lab Discussion The amount of air that you move in and out of your lungs depends on how quickly you are breathing. 2. 9. The data obtained may be even more inaccurate as those obtained using a spirometer. With the help of a few simple household objects, some scientific know how and a dash of curiosity you can make this experiment look easy. Vital Capacity is the maximum air moved in and out of the lungs. The tidal volume is the amount of air exchanged during a normal breath. Lab #17H - Lung Volumes and Capacities Measurement of lung volumes provides a tool for understanding normal function of the lungs as well as disease states. Balloon Lung. Carefully pull the balloon at the base of the bottle up and down and watch as the other balloon inflates. Several different lung volume measurements can be made. 7. Lung Capacity Lab NAME: Human lung capacity – or how much air can fit in your lungs – can be measured in several ways. 2 0 obj Measurement of Lung Capacity Lab Materials: String for measuring, ruler, round balloons, calculator Procedure: 1. d.write(', '); Measure and record the balloon's diameter as your Expiratory reserve. Breathing is the physical process of inhaling and exhaling. var iframe = "&fr=" + (window != top); Repeat this so that you have 3 total measurements and can take the average and record in the data table. var height = window.innerHeight || (window.document.documentElement.clientHeight || window.document.body.clientHeight); Air cannot go in or out. You will complete a lab that mixes a virtual component with a hands-on component. Take a deep breath and then exhale into the balloon. The amount of air that is moved in and out of the lungs when a person is breathing normally is called the tidal volume. The amount of air that is moved in and out of the lungs when a person is breathing normally is called the tidal volume.

Let's test your lung volume to find out. Blow it up and release it several times to stretch it. Do not force your breathing. Get Essay . Lung Capacity Lab Statement of the Problem: Measure your Tidal volume and Vital capacity. 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. endobj One way is by using a piece of laboratory equipment called a respirometer or spirometer. Procedure A: VITAL CAPACITY 1. Using a balloon you will take several different lung measurements: VITAL CAPACITY The largest possible amount of air which can be exhaled after drawing in a deep breath. Measure the balloon's diameter as your Tidal volume. This amount of air provides enough oxygen for the body when the person is resting. ref = "&rf="+escape(d.referrer); d.write('
