List I (Respiratory Volume) List II (Capacity in mL) A. ERV (Expiratory Reserve Volume) I. 2500 - 3000 mL B. RV (Residual Volume) II. 500 mL C. IRV (Inspiratory Reserve Volume) III. 1000 - 1100 mL D. TV (Tidal Volume) IV. 1100 - 1200 mL
Choose the correct answer from the options given below :
The question requires matching respiratory volumes from List I with their corresponding capacities in milliliters (mL) from List II.
Respiratory Volumes Matching Solution
Matching Respiratory Volumes and Capacities
To solve this, we need to identify the typical values for each respiratory volume:
- Tidal Volume (TV): The volume of air inhaled or exhaled during a normal breath. It is typically around 500 mL. (Matches with II)
- Expiratory Reserve Volume (ERV): The additional volume of air that can be forcefully exhaled after a normal exhalation. It is typically around 1000 - 1100 mL. (Matches with III)
- Inspiratory Reserve Volume (IRV): The additional volume of air that can be forcefully inhaled after a normal inhalation. It is typically around 2500 - 3000 mL. (Matches with I)
- Residual Volume (RV): The volume of air remaining in the lungs even after maximal exhalation. It is typically around 1100 - 1200 mL. (Matches with IV)
Correct Matches Found
Based on the typical values:
- A. ERV corresponds to 1000 - 1100 mL (III)
- B. RV corresponds to 1100 - 1200 mL (IV)
- C. IRV corresponds to 2500 - 3000 mL (I)
- D. TV corresponds to 500 mL (II)
Therefore, the correct matching is A-III, B-IV, C-I, D-II.
| List I (Respiratory Volume) | List II (Capacity in mL) |
| A. ERV | III. 1000 - 1100 mL |
| B. RV | IV. 1100 - 1200 mL |
| C. IRV | I. 2500 - 3000 mL |
| D. TV | II. 500 mL |
This corresponds to Option 2 in the choices provided.
