emphysema emphysema. A disease in which the alveoli (tiny air sacs) of the lungs are damaged. Their separating walls are destroyed and the alveoli are enlarged.This leads to a decrease in the surface area available for gas exchange, and breathing becomes very difficult.mphysema.

- Smoking Is a Major Cause of Emphysema. In the vast majority of people, smoking is the cause of emphysema. Exactly how smoking destroys the air sac linings in the lungs isn't known. However, population studies show that smokers are about six times more likely to develop emphysema than nonsmokers.

What is emphysema? Emphysema is a type of chronic obstructive pulmonary disease (COPD). It involves the loss of elasticity and enlargement of the air sacs in the lung. The alveoli at the end of the bronchioles of the lung become enlarged because their walls break down or the air sacs are destroyed, narrowed, collapsed, stretched, or over-inflated.

Definition of 'emphysema' uncountable noun. 1  Emphysema is a serious medical condition that occurs when the lungs become larger and do not work properly, causing difficulty in breathing. 2  a condition in which the air sacs of the lungs are grossly enlarged, causing breathlessness and wheezing. 3  the abnormal presence of air in a tissue or part.

Emphysema Definition and Information Emphysema is a common type of COPD in which the alveoli, or air sacs of the lungs, become damaged causing them to enlarge and burst. Because the air sacs are the cells in the lungs where oxygen and carbon dioxide are exchanged, damage in this area makes it difficult for people with emphysema to expel air from their lungs. This causes a build up of carbon dioxide in the body.

- For other uses, see Emphysema (disambiguation). Chronic obstructive pulmonary disease (COPD) is a type of obstructive lung disease characterized by long-term poor airflow. The main symptoms include shortness of breath and cough with sputum production. COPD is a progressive disease, meaning it typically worsens over time.

- Emphysema results when the delicate linings of the air sacs in the lungs become damaged beyond repair. Most commonly, the toxins in cigarette smoke create the damage. As the fragile tissues between air sacs are destroyed, air pockets in the lungs develop.

Smoking cessation health centre Emphysema. Emphysema is a long-term, progressive disease of the lungs that primarily causes shortness of breath. In people with emphysema the lung tissues necessary to support the physical shape and function of the lung are damaged.mphysema is called an obstructive lung disease because the destruction of lung tissue around smaller airways, called bronchioles, makes these airways unable to hold their shape properly when you exhale. This makes them inefficient at transferring oxygen into the blood, and in taking carbon dioxide out of the blood.

emphysema A. It's a chronic lung disease, characterized by destruction of the walls of the air sacs (alveoli) where the blood exchange oxygen and CO2 with the air. The disease leads to obstruction of the airflow, air trapping inside the lungs, and to many long term complications, and eventually to death.

- Emphysema is a form of chronic (long-term) lung disease, usually caused by smoking. Because of lung damage, people with emphysema have difficulty blowing air out. The major symptom of emphysema is shortness of breath. In most people, symptoms of emphysema are slowly progressive.

- The alveoli in the lungs are tiny air sacs where the exchange of oxygen and carbon dioxide takes place. Emphysema is diagnosed when the walls of these sacs lose elasticity and become inflamed.

What Are the Stages of Emphysema? Smoking is the most common cause of a serious lung condition called emphysema. With emphysema, the air sacs (alveoli) weaken and lose their ability to contract after expanding. Air can also get trapped in these sacs, causing some to break. This can make breathing difficult and ultimately decrease the amount of oxygen you get into your blood stream.

Emphysema Emphysema is one of the diseases that comprises COPD (chronic obstructive pulmonary disease). Emphysema involves gradual damage of lung tissue, specifically thinning and destruction of the alveoli or air sacs. Air sacs are destroyed in emphysema, making it progressively difficult to breathe.
