If there was a hole in structure B, the lung would collapse. This is because the negative pressure created by the pleural space (the space between the lung and the chest wall) is crucial for keeping the lung inflated. If air enters this space through a hole, it disrupts the balance of pressure and can cause the lung to collapse.
