GCSE PE- Lung volumes Spirometer trace

The video tutorial covers the concept of lung volumes, including tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. It explains how these volumes are measured using a spirometry trace and how they change during exercise. The tutorial emphasizes that while tidal volume increases with exercise, residual volume remains constant. The video concludes with a call to action for viewers to subscribe and follow on social media.

Which of the following is NOT one of the four main lung volumes discussed in the video?

• Vital Capacity

• Inspiratory Reserve Volume

• Tidal Volume

• Expiratory Reserve Volume

What happens to tidal volume during exercise?

• It disappears

• It remains the same

• It decreases

• It increases

What is the purpose of a spirometry trace?

• To visualize lung volumes

• To assess muscle strength

• To measure heart rate

• To calculate blood pressure

Why does residual volume remain constant even during exercise?

• It is the air that can be forcefully inhaled

• It prevents the lungs from collapsing

• It is the total lung capacity

• It is the air that can be forcefully exhaled

How does exercise affect inspiratory and expiratory reserve volumes?

• Inspiratory reserve volume decreases, expiratory reserve volume decreases

• Both decrease

• Both increase

• Inspiratory reserve volume increases, expiratory reserve volume decreases
