Lungs Disease Types
Airway diseases affect the tubes (airways) that carry Oxygen and other gases into and out of the lungs. These diseases cause a narrowing or blockage of the airways. They include asthma, emphysema and chronic bronchitis. People with airway disease sometimes describe the feeling as trying to breathe out through a straw.
Lung tissue diseases affect the structure of the lung tissue. Scarring or inflammation of the Tulsa makes the lungsunable to expel fully (’’restrictive lung disease’’).It also makes the lung less capable of taking up oxygen (oxygenation) and releasing carbon dioxide. Pulmonary fibrosis and sarcoidosis are examples of interstitial lung disease.
Pulmonary Vascular diseases affect the blood vessels in the lungs. They are caused by clotting, scarring, or inflammation of the blood vessels(e.g primary pulmonary hypertension,chronic thromboembolic disease), They affect the ability of the lungs to take inoxygen and release carbon dioxide. These diseases may also affect heart functions
What is COPD?
In chronic obstructive pulmonary disorder (COPD) , breathing tubes that carry air in and out of the lungs are obstructed.With COPD, sacs lose their elasticity and collapseor do no inflate properly.Furthermore, COPD is characterized by mucus blockage of the breathing tubes as well as swelling, preventing air flow.
What is Asthma?
Asthma is a chronic disease that effects the airways, which causes breathing problems, and can be life
The inside walls of the airways are inflamed (swollen). The inflammation makes the airways very sensitive, increasing their tendency to react strongly to allergens or be irritated.
Increased airway The inside walls of the airways are inflamed (swollen). The inflammation makes the airways very sensitive, increasing their tendency to react strongly to allergens or be irritated.
responsiveness after an allergen challenge causes itto get narrower and less air flows through to the lung tissues. This causes symptoms like wheezing (a whistling sound when you breathe), coughing, chest tightness, and trouble breathing.
What happens during an asthma attack?
During an asthma attack, the smooth muscles in the airways become thicker (smooth muscle hypertrophy)due to increased mucous production and cause the airwaysto become restricted. Inflammation causes immune cells( Mast cells, Neutrophills) to go to the affected area and release chemicals which cause swelling and fluid leakage
