To match each pulmonary measurement with its correct description, we can follow these steps:
1. Expiratory Reserve Volume (ERV)
- This is the amount of air, in excess of tidal volume, that can be exhaled with maximal effort.
- Therefore, the correct match is (1, e).
2. Residual Volume (RV)
- This represents the amount of air remaining in the lungs after normal tidal expiration.
- Hence, the correct match is (2, b).
3. Vital Capacity (VC)
- Vital Capacity is measured as the total amount of air that can be expelled from the lungs after maximal inhalation, typically represented as (TV + ERV).
- The correct match is (3, a).
4. Inspiratory Capacity (IC)
- This is described as the deepest breath possible, the maximum amount of air that can be inspired from the end of a normal, quiet expiration.
- Thus, the correct match is (4, g).
5. Functional Residual Capacity (FRC)
- This refers to the amount of air remaining in the lungs after maximal expiration.
- Therefore, the correct match is (5, c).
6. Total Lung Capacity (TLC)
- Total Lung Capacity is obtained by adding the Vital Capacity (VC) and the Residual Volume (RV).
- Hence, the correct match is (6, f).
7. Tidal Volume (TV)
- Tidal Volume is the amount of air inhaled or exhaled in one breath during quiet breathing.
- Consequently, the correct match is (7, d).
8. Inspiratory Reserve Volume (IRV)
- Inspiratory Reserve Volume is obtained by subtracting ERV from VC.
- The correct match is (8, j).
9. Forced Expiratory Volume (FEV)
- This is measured by having the subject rapidly exhale into a spirometer.
- Thus, the correct match is (9, i).
10. Minute Respiratory Volume (MRV)
- Minute Respiratory Volume is a measure related to the alveolar ventilation rate.
- Therefore, the correct match is (10, h).
Putting it all together, the final matches are:
1. (1, e)
2. (2, b)
3. (3, a)
4. (4, g)
5. (5, c)
6. (6, f)
7. (7, d)
8. (8, j)
9. (9, i)
10. (10, h)
