In the lungs, airways partially blocked

Chronic obstructive pulmonary disease (COPD) is a disease in which airways and tiny air sacs () inside a partially stopped or destroyed. The result is difficulty breathing. There are different stages of the disease, and different names for them, but returned to the damaged airways and air sacs. This disease occurs when a person breathes in lung irritants some: smoke, chemicals, pollution, dust. It makes sense then that the most common cause of COPD is smoking. In our easy to look down the tree trunks at the top, tapering to tiny branches at the bottom. At the ends of branches, thousands of tiny round air sacs. In healthy people, goes to the bags are clear and open. Sacks is resilient and strong. When we take a breath, fill bags like little balloons, and swell when we exhale. In the lungs, airways partially blocked, and air bags are floppy and form. When a person inhales, bags do not fill as well, resulting in shortness of breath. One or all of these things can occur in the lungs:

airways and air sacs lose elasticity, as the old gum can

Cell airways make more mucus [phlegm] and airway obstruction because of this. Chronic occurs when the airways become inflamed and thickened. More cells in the airways make mucus, as a result of habitual cough and shortness of breath. This is what is happening more and more walls between air sacs are destroyed. Instead, many small bags, and destroy what remained of smaller bags. These large bags are less surface area to exchange oxygen and carbon dioxide than smaller ones. Poor exchange of oxygen and carbon dioxide causes shortness of breath. Often people with COPD and chronic bronchitis and emphysema. The majority of smokers and former smokers. This disease develops slowly, with repeated exposure light stimuli. Most people do not begin to manifest symptoms until they are 40 years or older.
