Difference between bronchial asthma, chronic bronchitis and emphysema in terms of lung?

Difference... Asthma is characterized by recurrent, reversible airway obstruction. Emphysema and chronic bronchitis are both forms of COPD and are characterized by irreversible airway obstruction usually caused by smoking. Now, COPD patients can also have a reversible airway obstruction component and asthmatics can develop an irreversible component over time so there is overlap in this definition.
Lung. Ask a pulmonologist. This question is too broad. We can have ground rounds on this question and not have an answer. As a pcp i try to help you based on your symptoms and medical history. Since you have a complex question, then i prefer you see a pulmonologist. Again, regardless of a specific answer, treatment are many times similar. Good luck.
