Asthma is inflammation of bronchioles. Its symptoms include wheezing. coughing and difficulty in breathing mainly during expiration.
Emphysema is an inflation or abnormal distension of the bronchioles or alveolar sacs of the lungs.

As a result alveolar septa collapse and the surface area get greatly reduced.
