What are the three morphological changes that occur in people with emphysema?


1. The first morphological change affects the alveoli of the lungs. The walls of the alveoli break down, and clusters of alveoli become a single sac.

2. The second morphological change arises as a result of the first change. The person experiences an ongoing shortage of oxygen, must breathe deeper and deeper to accommodate, and thus develops a "barrel chest."


3. The third morphological change results in respiratory failure, which leaves the person susceptible to respiratory disorders such as pneumonia.
