Emphysema is characterized by loss of elasticity

Chronic obstructive pulmonary disease (COPD) is a general term for a group of diseases of the airways that is characterized by airway obstruction or limitation. Usually caused by smoking tobacco, but can also be caused by coal dust, among other incentives.

As a result of small airways collapse during exhalation, resulting in obstructive form of lung disease in which air trapped in the lungs. Symptoms include shortness of breath on exertion - particularly when climbing stairs or inclines (and later at rest), hyperventilation and chest expansion.
