Taking the Test: 1  Never leave an answer blank on a short answer or essay test. 2  If you arenât sure what an answer to a question is, skip it and come back to it later. 3  If you are really confused about a question, ask your professor for clarification.  After you answer a question, reread the question.
COPD is a type of obstructive lung disease in which chronic incompletely reversible poor airflow (airflow limitation) and inability to breathe out fully (air trapping) exist. The poor airflow is the result of breakdown of lung tissue (known as emphysema) and small airways disease (known as obstructive bronchiolitis).hronic obstructive pulmonary disease may occur in a number of other animals and may be caused by exposure to tobacco smoke. Most cases of the disease, however, are relatively mild. In horses it is also known as recurrent airway obstruction and is typically due to an allergic reaction to a fungus contained in straw.
Chronic obstructive pulmonary disease or COPD refers to respiratory (lung) diseases that cause breathing difficulties and block airflow from the lungs. Chronic bronchitis (inflammation and narrowing of the bronchial tubes) and emphysema (damage to the lining of the air sacs in the lungs) are the two most common types.hronic obstructive pulmonary disease or COPD refers to respiratory (lung) diseases that cause breathing difficulties and block airflow from the lungs.
