Question
Using the data collected from the data table explain physiologically why the tidal volume is the same in the normal and emphysema case but is decreased during the acute asthma attack and why the inhaler worked to return tidal volume to normal levels.

TV increases as there are so many of the walls of the alveoli have been destroyed, they are like giant floppy bags instead of nice firm bubbles. There's more empty space, and the total volume is thus increased.RV and End Respiration Volume increase because these alveoli are large and stretched and floppy and can't push as much air out, even when you try. (Decreased elastic recoil.) They also flop shut often before the air is expelled - trapping air in.TV may not change at all, but it takes longer to exhale than with normal lungs. That is why FEV1 and FVC are lower, for the same reason.
Exercise-induced asthma is a narrowing of the airways in the lungs that is triggered by strenuous exercise. It causes shortness of breath, wheezing, coughing and other symptoms during or after exercise. The preferred term for this condition is exercise-induced bronchoconstriction. Inhaler helps the airways to regain their diameter and smoothen the breath and hepls the patient to respire normally.
