It features an orientation figure to show the position of the lungs in the chest. The weakened and ruptured air sacs are unable to efficiently move oxygen from the air to the blood. Both static and dynamic effects of breathing contribute to lung hyperinflation in COPD. In order to see how COPD impairs lung function, it helps to understand how the lungs function and what they look like when they're healthy.

The distensibility estimated during normal tidal breathing from measurements of lung volume and esophageal pressure made at the end of inspiration and expiration when the lungs are apparently stationary has an index as a result, which is called dynamic compliance. That means your airways can’t filter the dust and dirt in the air you breathe.
