What is distinguish between asthma and emphysema?

Answer 1

Asthma and emphysema are two entirely different diseases with some symptoms in common. Asthma is a spastic and inflammatory disease of the airways that causes reversible obstruction of the bronchial tubes. It usually responds to treatment.

Emphysema is a disease of the lung tissue, especially the alveoli (air sacs) at the end of the bronchial tubes. Emphysema results from destruction of these alveoli. This process is not reversible and responds less well to medical treatment. Emphysema is slowly progressive; you will get short of breath and become more disabled as time goes on. Eventually you may require continuous concentrated oxygen to be comfortable. This irreversible disease (and other obstructive lung diseases such as chronic bronchitis) is often referred to as chronic obstructive pulmonary disease (COPD).

Answer 2

Atelectasis, a Greek word meaning "incomplete extension" the collapse or closure of the lung resulting in reduced or absent gas exchange . It may affect part or all of one lung. It is a condition where the alveoli are deflated. its d inability of the lung to expand completely. Acute atelectasis may occur as a post-operative complication or as a result of surfactant deficiency. In premature neonates, this leads to infant respiratory distress syndrome.

Emphysema a Greek word meaning "inflate" a chronic medical disorder of the lungs in which the air sacs are dilated or enlarged and lack flexibility, so that breathing is impaired and infection sometimes occurs cos the tissues necessary to support the shape and function of the lungs are destroyed. It is most often caused by tobacco smoking and long-term exposure to air pollution.

Answer 3

Emphysema and chronic bronchitis are sub-categories of COPD. If you have either, you have COPD.
