Fig. Breathing (inspiration and expiration) occurs in a cyclical manner due to the movements of the chest wall and the lungs. It refers to the average age of a nonsmoker with a forced expiratory volume at 1 second (FEV1) equal to that of the person being tested. Lung volumes measurement is an integral part of pulmonary function test. In addition to men of average height, men were selected who were unusually tall, including 15 who Lung volume is the total amount of air that you can breathe out after taking a deep breathe in. Females have a 20 to 25 percent lower total lung capacity than males on average, and people who smoke also have much lower lung capacities, states The Physics Factbook.
