Differentiate between
A) Inspiratory and Expiratory Reserve Volume
B) Vital Capacity and Total Lung Capacity
C) Emphysema and occupational respiratory disorder
A)
Inspiratory Reserve volume |
Expiratory Reserve Volume |
Additional volume of air a person can inspire by a forcible inspiration is called inspiratory reserve volume (IRV). |
Additional volume of air a person can expire by a forced expiration is called expiratory reserve volume (ERV). |
In a normal individual, IRV is about 2500 to 3000 mL |
In a normal human, ERV is about 1000 to 1100 mL. |
B)
Vital capacity |
Total Lung Capacity |
The maximum volume of the air one can breathe after a forceful expiration, is called Vital Capacity. |
The total volume of air in lungs at the end of a forced inspiration is called Total Lung Capacity. |
C)
Emphysema |
Occupational Respiratory disorder |
Alveoli walls are damaged in emphysema |
any other part of the respiratory system is damaged in occupational respiratory disorder |
Caused due to smoking |
Caused due to fine particles generated |
