Observe the given spirogram where specific respiratory capacities and volumes are indicated by brackets labeled A, B, C, and D. Match the labels in List I with their corresponding terms in List II.
| List I | List II | ||
|---|---|---|---|
| A | Label A | I | Functional residual capacity |
| B | Label B | II | Vital capacity |
| C | Label C | III | Residual volume |
| D | Label D | IV | Inspiratory capacity |
Choose the correct answer from the options given below :
Options
- AA-IV, B-III, C-II, D-I
- BA-II, B-I, C-IV, D-III
- CA-I, B-IV, C-II, D-III
- DA-IV, B-I, C-II, D-III
Correct answer
D. A-IV, B-I, C-II, D-III
Step-by-step solution
Label A represents the total volume of air a person can inspire after a normal expiration. This is the sum of tidal volume and inspiratory reserve volume, which is known as inspiratory capacity. Thus, A matches with IV.
Label B represents the volume of air that remains in the lungs after a normal expiration. This is the sum of expiratory reserve volume and residual volume, which is known as functional residual capacity. Thus, B matches with I.
Label C represents the maximum volume of air a person can breathe out after a forced inspiration. This is the sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume, which is known as vital capacity. Thus, C matches with II.
Label D represents the volume of air remaining in the lungs even after a forcible expiration. This is the residual volume. Thus, D matches with III.
Answer: A-IV, B-I, C-II, D-III.
Label B represents the volume of air that remains in the lungs after a normal expiration. This is the sum of expiratory reserve volume and residual volume, which is known as functional residual capacity. Thus, B matches with I.
Label C represents the maximum volume of air a person can breathe out after a forced inspiration. This is the sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume, which is known as vital capacity. Thus, C matches with II.
Label D represents the volume of air remaining in the lungs even after a forcible expiration. This is the residual volume. Thus, D matches with III.
Answer: A-IV, B-I, C-II, D-III.
