Answer:
The residual volume is the amount of air remaining in the lungs after a forced expiration.
The volume of air exchanged during normal breathing is called the tidal volume.
After a normal inspiration, the amount of air that can then be inspired forcefully is called the inspiratory reserve volume .
If you subtract the residual volume from the total lung capacity, you get the vital capacity.
The vital capacity minus the expiratory reserve volume equals the inspiratory capacity.
The effects of obstructive diseases such as asthma or emphysema may be determined by measuring the forced expiratory volume .
