- Pathologic changes in chronic obstructive pulmonary disease (COPD) occur in the large (central) airways, the small (peripheral) bronchioles, and the lung parenchyma. Most cases of COPD are the result of exposure to noxious stimuli, most often cigarette smoke.

Overview Pulmonary fibrosis scars and thickens the tissue around and between the air sacs (alveoli) in your lungs. This makes it more difficult for oxygen to pass into your bloodstream. The damage can be caused by many different factors — including long-term exposure to certain toxins, certain medical conditions, radiation therapy and some medications.

Chronic Obstructive Pulmonary Disease (Chronic Bronchitis; Emphysema) Chronic obstructive pulmonary disease is persistent narrowing (obstruction) of the airways occurring with emphysema, chronic obstructive bronchitis, or both disorders. Cigarette smoking is the most important cause of chronic obstructive pulmonary disease.

asthma In an asthma attack, the muscle tissue in the walls of bronchi go into spasm, and the cells lining the airways swell and secrete mucus into the airways. Both these actions cause the bronchi to become narrowed (bronchoconstriction).

bronchiectasis The bronchial tubes are the networks of branching tubes which deliver air to the tiny sacs of the lungs (alveoli). In bronchiectasis, the diameter of the bronchi is unusually large. Examination of the walls of the bronchial tubes reveals destruction of the normal structural elements, with replacement by scar tissue.ymptoms of bronchiectasis include constant cough and the production of infected sputum (sputum is a mixture of mucus and pus), which may be bloody. In some cases, there may be wheezing and shortness of breath.

- The first is intrinsic lung diseases or diseases of the lung parenchyma. The diseases cause inflammation or scarring of the lung tissue (interstitial lung disease) or result in filling of the air spaces with exudate and debris (pneumonitis). These diseases can be characterized according to etiological factors.estrictive lung diseases are characterized by a reduction in FRC and other lung volumes because of pathology in lungs, pleura, or the structures of the thoracic cage. The distensibility of the respiratory system is called compliance, the volume change produced by a change in the distending pressure.

Overview COPD causes them to lose their elasticity and overexpand, which leaves some air trapped in your lungs when you exhale. 1  Emphysema. Emphysema Emphysema damages the inner walls of the lungs' air sacs (alveoli), causing them to eventually rupture. 2  Bronchitis.

An Overview of Bronchiectasis Bronchiectasis often begins with repeated respiratory infections in childhood. These infections result in a thickening, widening, and scarring of the bronchi - the tubes which pass from the trachea and down into the alveoli, the area in the lungs where the exchange of oxygen and carbon dioxide takes place.

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.

Bronchiolitis Bronchiolitis is an infection that causes the small breathing tubes of the lungs (bronchioles) to swell. This blocks airflow through the lungs, making it hard to breathe. It occurs most often in infants because their airways are smaller and more easily blocked than in older children.

5 Main Causes Of Hyperinflation Of Lungs People with obstructive pulmonary disease have increased chances of developing hyperinflation of the lungs. COPD results from co-existence of chronic bronchitis and emphysema. It is a progressive disease and generally gets worse with time.hronic bronchitis results due to inflammation of the bronchi. Acute or chronic bronchitis results due to viral or bacterial infection in the bronchi which conduct air into the lungs. Chronic bronchitis can also result due to environmental factors and exposure to chemicals.

Respiratory Diseases: COPD, Asthma & Allergies | Newsletter In emphysema, the walls between many of the air sacs are damaged. As a result, the air sacs lose their shape and become floppy. This damage also can destroy the walls of the air sacs, leading to fewer and larger air sacs instead of many tiny ones. If this happens, the amount of gas exchange in the lungs is reduced.

Overview Emphysema gradually damages the air sacs (alveoli) in your lungs, making you progressively more short of breath. Emphysema is one of several diseases known collectively as chronic obstructive pulmonary disease (COPD). Smoking is the leading cause of emphysema. Your lungs' alveoli are clustered like bunches of grapes. In emphysema, the inner walls of the air sacs weaken and eventually rupture — creating one larger air space instead of many small ones. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches your bloodstream.

- With chronic bronchitis, the bronchial tubes become inflamed and scarred. With emphysema, the air sacs in the lungs are slowly destroyed. With both disorders, those affected experience increasing difficulty exhaling and getting a sufficient oxygen supply. Smoking causes about 85-90% of the deaths associated with COPD. Other risk factors include repeated exposure to air pollution.

bronchiole The bronchioles or bronchioli are the passageways by which air passes through the nose or mouth to the alveoli (air sacs) of the lungs, in which branches no longer contain cartilage or glands in their submucosa.he diameter of the bronchioles plays an important role in air flow. The bronchioles change diameter to either increase or reduce air flow. An increase in diameter is called bronchodilation and is stimulated by either epinephrine or sympathetic nerves to increase air flow.

NCI Dictionary of Cancer Terms In reactive airway disease, three primary changes are taking place in your lungs: Increased Mucus: Your airways become irritated and inflamed, causing the cells in your airways to produce mucus. The thick mucus produced can clog the airways of your lung, making it difficult to breathe.

Pulmonary emphysema Pulmonary emphysema is defined as the abnormal permanent enlargement of the airspaces distal to the terminal bronchioles accompanied by destruction of the alveolar wall and without obvious fibrosis. Emphysema is one of the entities grouped together as chronic obstructive pulmonary disease.

Bronchiectasis Cystic fibrosis eventually results in severe bronchiectasis in nearly all cases. The cause in 10-50% of those without cystic fibrosis is unknown. The mechanism of disease is breakdown of the airways due to an excessive inflammatory response.Involved bronchi become enlarged and thus less able to clear secretions.ronchiectasis is a disease in which there is permanent enlargement of parts of the airways of the lung. Symptoms typically include a chronic cough productive of mucus. Other symptoms include shortness of breath, coughing up blood, and chest pain. Wheezing and nail clubbing may also occur.

Bronchitis Bronchitis is a general term for two diseases that cause swelling and irritation (inflammation) of the lower airways of the lungs called the bronchi and the bronchioles. Types of bronchitis include chronic bronchitis and acute bronchitis. Chronic bronchitis is a progressive, recurring inflammation of the lungs, most often due to the damage that long-term smoking causes to the lungs. Chronic bronchitis is a type of chronic obstructive pulmonary disease and is most common in long-term smokers.

- Pulmonary bullous disease involves the presence of what the Mayo Clinic calls holes in the normal lung tissue. These air sacs, also called bullae, usually occur in conjunction with emphysema--a debilitating lung condition characterized by wheezing, coughing, shortness of breath, a tight feeling in the chest and other signs of respiratory distress.

Bronchiectasis: Current Concepts in Pathogenesis, Immunology, and Microbiology Bronchiectasis is an obstructive lung disease that presents with chronic cough and sputum production, recurrent bacterial infection, tiredness, and progressive lung damage. It is the result of a complex interplay between host immunity, pathogen, and environment.
