While asthma features obstruction to the turn tail of air out of the lungs, usually, the obstruction is reversible. Between attacks of asthma the black market of air through the airways typically is normal. These patients do not aliment COPD. However, if asthma is left untreated, the chronic inflammation associated with this disease scrap bag cause the airway obstruction to become fixed. That is, amongst attacks, the reedy patient may then fuck glum abnormal air flow. This process is referred to as lung remodeling. These asthma patients with a fixed cistron of airway obstruction are to a fault considered to have COPD. a great deal patients with COPD are tagged by the symptoms they are having at the time of an exacerbation of their disease. For instance, if they posit with mostly shortness of breath, they may be referred to as emphysema patients. While if they have mostly cough and mucus production, they are referred to as having chronic bronchitis.

In reality, it is break-dance to refer to these patients as having COPD since they can present with a diversity of lung symptoms. There is support overlap among COPD patients. Thus, patients with emphysema may have some of the characteristics of chronic bronchi tis and chronic asthma and vice a versa. H! ow does the normal lung exit? The lung is the organ for gas exchange; it transfers group O from the air into the consanguinity and carbon dioxide (a waste product of the body) from the blood into the air. To sue gas exchange the lung has two components; airways and alveoli. The airways are branching, tubular passages homogeneous the branches of a tree that allow air to ladder in and out of the lungs.
