The data you obtain may not be as accurate as that obtained using a spirometer though. Then, blow up and deflate your balloon several times. Data Table 1 Balloon Diameter (cm) Trial Tidal Vital Volume Capacity 1 2 3 Average Part C. Calculating Estimated Vital Capacity 1. The amount of air taken in or expelled during normal breathing is about 500 cm3. This lab is a replication of the lung capacity lab. Lung capacity is probably based on height and perhaps age. 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. #archive:hover { zoom:101%;) d.write('

Lung Capacity Lab Name _____ Your # _____ Human lung capacity can be measured in several ways. The data you obtain may not be as accurate as that obtained using a spirometer though. This amount of air provides enough oxygen for the body when the person is resting. Release the air from the balloon. Do not force your breathing. Several different lung volume measurements can be made: 1. rp_site = '17527'; 2. Page 1 of 4... 13-19 20-29 30-39 40-49 50-59 60+ Discussion Nelson Biology 11 page 466 (a)-(f) To determine the expiratory reserve volume (ERV) the following formula is used. Lung capacity can be measured by blowing up a balloon. Lung Capacity Lab NAME: Human lung capacity – or how much air can fit in your lungs – can be measured in several ways. The data you obtain may not be as accurate as that obtained using a spirometer though. One way is by using a piece of laboratory equipment called a respirometer or spirometer. The data obtained may be even more inaccurate as those obtained using a spirometer. This will make it easier for you to blow up your balloon during the experiment by removing some of the resistance. Take a normal breath and exhale a normal amount of air into the balloon. However, lung capacity can also be measured by using a balloon. The purpose of this lab is to determine our own lung capacity using a balloon. Ensure the entire neck of the bottle is covered to make an air-tight seal. Then before inhaling again, force air in your lungs into the balloon. if (window != top) { One way is by using a piece of laboratory equipment called a spirometer. Do not force your breathing. Stretch a balloon several times. Measuring Tidal Volume -- Stretch a round balloon several times to stretch it out. Tidal volume is the amount of air breathed in and out at rest, normal breathing. One way is by using a complex piece of laboratory equipment called a spirometer. Do not force your breathing. and = 3.14, Back to Biology Table of Contents
1. (To report any malicious content send the URL to oocities(at gmail dot com). Lung capacity can be measured by blowing up a balloon. 5. Lay the balloon on the table next to the ruler. You will make comparison of your resting and jogging vital capacities. Physics is responsible for filling your lungs with air. -o-transition: -o-transform 0.5s ease; information on lung health: Tidal volume – the amount of air taken in or expelled during normal breathing. Record in the DATA TABLE, 8. Purpose: This lab activity will allow you to determine your lung capacity. To convert from balloon diameter to volume, locate the balloon diameter on the horizontal axis of the graph on the next page. 7. -ms-transition: transform 0.5s ease;} Measure and record the balloon's diameter as your Expiratory reserve. One way is by using a piece of laboratory equipment called a respirometer or spirometer. Lab: Balloons and Lung Capacity Experiment BACKGROUND: Your respiratory system is a group of organs that work together to take oxygen into your body and get rid of carbon dioxide. 5"��$*AD�5ss {��:��;�,`�~��sMs]��yC����vJD�*2*½$"z��]���9t�K���\��

Once I placed the bucket in the center of the tray, I dunk the balloon into the water being careful in the process in order to not spill extra water into the tray. Several different lung volume measurements can be made. Lung Capacity Lab. d.write('
