How are emphysema and chronic bronchitis alike?

ANSWER

Emphysema and chronic bronchitis are both chronic obstructive pulmonary diseases (COPD) -- long-term conditions that cause a limitation in airflow, making it hard to breathe in and out. They can happen separately or together and are usually the result of years of cigarette smoking, though exposure to coal dust and cotton dust are also risk factors.
