Question:
Differentiate between
a. Inspiratory and expiratory reserve volume
b. Vital capacity and total lung capacity
c. Emphysema and occupational respiratory disorder
Solution:
a. Inspiratory reserve volume is the maximum volume of air that can be inhaled after normal inspiration whereas expiratory volume is the maximum volume of air that can be exhaled after normal exhalation.
b. Vital capacity is the maximum volume of air that can be exhaled after normal inspiration whereas total lung capacity is the volume of air in the lungs after maximum inspiration.
c. Emphysema is a disorder in which the alveolar walls are damaged whereas occupational respiratory disorder is caused due to the proliferation of the fibrous connective tissue of the upper lungs.
