Test Yourself

This quick 10-question quiz tests your understanding of the four lung volumes, four lung capacities, their normal values, and how they change in conditions like COPD and pulmonary fibrosis. Whether you're a physio student or just brushing up let's see how well your lungs of knowledge hold up!

What is the normal Total Lung Capacity (TLC) in a healthy adult? *

Select the normal Total Lung Capacity for a healthy adult.

5500 ml

4000 ml

3500 ml

7000 ml

This field is required.

What is the normal range of Vital Capacity in adults? *

Choose the normal range for Vital Capacity in adults.

5 to 7 litres

3 to 5 litres

2 to 3 litres

1 to 2 litres

This field is required.

Functional Residual Capacity (FRC) is the combination of: *

What components make up the Functional Residual Capacity?

RV + TLC

ERV + RV

IRV + TV + ERV

TV + IRV

This field is required.

What is the definition of Tidal Volume (TV)? *

Select the best definition of Tidal Volume.

Volume of air inhaled or exhaled during resting breathing

Total air the lungs can hold

Air remaining after maximum exhalation

Maximum air inhaled during forced inspiration

This field is required.

Inspiratory Reserve Volume (IRV) is best described as: *

Identify the best description for Inspiratory Reserve Volume.

Air expelled during forceful expiration

Extra air inhaled beyond tidal volume during forceful inspiration

Air left after normal expiration

Air remaining after maximum exhalation

This field is required.

Which lung capacity is calculated as TV + IRV? *

Select the lung capacity defined by the sum of Tidal Volume and Inspiratory Reserve Volume.

Inspiratory Capacity

Functional Residual Capacity

Total Lung Capacity

Vital Capacity

This field is required.

What is the normal value of Tidal Volume in a healthy adult? *

Choose the normal value of Tidal Volume for adults.

2500 ml

1500 ml

500 ml

1000 ml

This field is required.

How does ageing affect lung function? *

Choose the statement that best describes the effect of ageing on lung function.

Lung capacity increases with age due to respiratory muscle strengthening

Ageing has no significant effect on lung volumes

The lung matures by age 20–25, then progressively declines thereafter

Lung function peaks at age 40 and stays stable

This field is required.

In COPD, which volume characteristically increases due to air trapping? *

Select the volume that increases in COPD due to air trapping.

Residual Volume

Tidal Volume

Vital Capacity

Inspiratory Reserve Volume

This field is required.

In restrictive pulmonary disease (e.g., pulmonary fibrosis), what happens to lung capacities? *

Choose the effect of restrictive pulmonary disease on lung capacities.

All capacities are reduced

All capacities increase

Capacities remain normal

Only RV increases, others decrease

This field is required.
