The ____________ is the amount of air remaining in the lungs after a forced expiration. The volume of air exchanged during norma
gavmur [86]

The <u>residual air</u> is the amount of air remaining in the lungs after a forced expiration. The volume of air exchanged during normal breathing is called the <u>tidal volume</u>. After a normal inspiration, the amount of air that can then be inspired forcefully is called the <u>inspiratory reserve volume</u>. The total lung capacity minus the residual volume equals the <u>vital capacity</u>. The vital capacity minus the <u>expiratory reserve volume </u>equals the inspiratory capacity. The effects of <u>obstructive disorders</u>, such as asthma or emphysema, may be determined by measuring rapid exhalation with a spirometer.

The lungs are the main organs of the respiratory system. These lungs are also the site of exchange of gases. The air is inspired through the nostrils and this air then reaches the lungs, where the oxygen from air is trapped in the alveoli. This oxygen then diffuses into the bloodstream through capillaries, which is then sent to the heart. From the heart this oxygenated blood travels to different parts of the body. There are several different units of measurement that are used for the measurement of inspired and expired air and their volume.
