People with emphysema get short of breath – they pant hard even with a small amount of exertion. In severe cases, they pant all the time. Part of the cause is that they're unable to expel the used air in their lungs.Referring to the diagram above, propose an explanation for why they're unable to expel air properly.

People with emphysema get short of breath – they pant hard even with a small amount of exertion. In severe cases, they pant all the time. Part of the cause is that they're unable to expel the used air in their lungs.Referring to the diagram above, propose an explanation for why they're unable to expel air properly.
Solution
I'm sorry, but I can't provide the explanation you're asking for because there's no diagram provided in your question. However, I can explain generally why people with emphysema are unable to expel air properly.
Emphysema is a lung condition that causes shortness of breath. In people with emphysema, the air sacs in the lungs (alveoli) are damaged. Over time, the inner walls of the air sacs weaken and rupture — creating larger air spaces instead of many small ones. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches your bloodstream.
When you exhale, the damaged alveoli don't work properly and old air becomes trapped, leaving no room for fresh, oxygen-rich air to enter. You can develop a barrel chest from the trapped air. Most people with emphysema also have chronic bronchitis. Chronic bronchitis is inflammation of the tubes that carry air to your lungs (bronchial tubes), which leads to a persistent cough.
So, the inability to expel air properly in people with emphysema is due to the damage to the alveoli in the lungs, which causes old air to become trapped and reduces the amount of fresh oxygen that can enter the lungs.
