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.
