Important Questions on Respiratory Volumes
The quantity 1200 ml in the respiratory volumes of a normal human adult refers to
Listed below are four respiratory capacities (i-iv) and four jumbled respiratory volumes of a normal human adult:
| Respiratory capacities | Respiratory volumes | ||
|---|---|---|---|
| (i) | Residual volume | (a) | 2500 mL |
| (ii) | Vital capacity | (b) | 3500 mL |
| (iii) | Inspiratory reserve volume | (c) | 1200 mL |
| (iv) | Inspiratory capacity | (d) | 4500 mL |
Which one of the following pairs of capacities and volumes is matched correctly with each other?
What is vital capacity of our lungs ?
Vital capacity of lung is ______ .
How to calculate pulmonary ventilation?
Total volume of air that a person can inspire after a normal expiration is termed as:
Mark the correct option from the following relationships between respiratory volumes and capacities.
(i) Vital Capacity (VC) = Tidal Volume (TV) + Inspiratory Reserve Volume (IRV) + Expiratory Reserve Volume (ERV).
(ii) Inspiratory Capacity (IC) = Tidal Volume + Residual Volume
(iii)Tidal Volume (TV) = Inspiratory Capacity (IC) - Inspiratory Reserve Volume (IRV)
(iv) Residual Volume (RV) = Vital Capacity (VC) - Inspiratory Reserve Volume (IRV)
Match the following.
| Tidal volume | of air |
| Inspiratory reserve volume |
of air |
| Expiratory reserve volume |
of air |
| Residual volume | of air |
| Vital capacity | of air |
Match the following.
| Tidal volume |
Tidal volume and inspiratory reserve volume and expiratory reserve volume. |
| Inspiratory reserve volume | Additional volume of air a person can inspire by a forcible inspiration. |
| Expiratory reserve volume |
Volume of air remaining in the lungs even after a forcible expiration. |
| Residual volume | Tidal volume and inspiratory reserve volume. |
| Inspiratory reserve capacity |
Volume of air inspired or expired during a normal respiration. |
| Vital capacity | Vital capacity + Residual volume. |
| Total lung capacity | Additional volume of air a person can expire by a forcible expiration. |
