Lung irritants damage the alveoli which are tiny hollow air sacs.. In emphysema, the air sacs begin to collapse, which reduces the amount of surface area where gas exchange occurs. The person coughs because the lungs feel irritated and tight, like in Asthma, and the person may have wheezing.
Most emphysema causes involve repeated breathing in of fumes and other things that irritate and damage the lungs and airways.
Specific causes of emphysema can include:
Smoking
Cigarette smoking is the most common irritant that causes emphysema. Pipe, cigar, and other types of tobacco smoking can also cause emphysema, especially if the smoke is inhaled.
Fumes and Dust
Breathing in other fumes and dusts over a long period of time may also cause the disease. The lungs and airways are highly sensitive to these irritants. They cause the airways to become inflamed, narrowed, and destroy the elastic fibers that allow the lung to stretch, then come back to its resting shape. This makes breathing air in and out of the lungs more difficult.
Other things that may irritate the lungs and contribute to emphysema include:
Genetic Factors
Genes (tiny bits of information in your body's cells passed on by your parents) may play a role in developing emphysema.
In rare cases, emphysema is caused by a gene-related disorder called alpha-1 antitrypsin deficiency. Alpha-1 antitrypsin is a protein in your blood that inactivates destructive proteins in the blood. People with antitrypsin deficiency have low levels of alpha-1 antitrypsin; the imbalance of proteins leads to the destruction of the lungs. If people with this condition smoke, the disease progresses more rapidly.
causes of emphysema are smoking, infections ,working place pollution,etc
acinus desry the alvli and smoking is mager cause of emphysema
Yes, airborne chemicals can cause emphysema. See related link below.

Emphysema IS a respiratory problem. Emphysema is one of many conditions that are collectively called COPD, Chronic Obstructive Pulmonary Disease.
emphysema
The exact causes is still not known but it is believed to be caused by inhalation of polutant. These stuffs cause immune reaction that somehow destroy your alveoli. And/or smoking can cause emphysema, weakening/eating away the thin skin tissue of your lungs.

Emphysema is a disease that destroys the tiny air sacs in your lungs. In this case it can even cause lung cancer. A person with advanced emphysema uses 80% of his/her energy to breathe.
