How would an individual with emphysema affect each of the following respiratory volumes: a. tidal volume: b. expiratory reserve volume: c. vital capacity:

Here's how an individual with emphysema affects each of the following respiratory volumes: 
a.Tidal Volume: The Tidal Volume will decrease
b.Expiratory Reserve Volume: The ERV will decrease
c.Vital Capacity: The Vital capacity will decrease
In this kind of disease, the lung tissue involved in the exchange of gases (oxygen and carbon dioxide) is not performing at its capacity.
