CHRONIC OBSTRUCTIVE PULMONARY DISEASE Have you ever known a person who smokes and has a hard time doing every day activities, due to difficulty of breath, or constantly coughing. He or she may have Chronic Obstructive Pulmonary Disease, or COPD. COPD is a progressive and treatable lung disease that causes shortness of breath due to obstruction of air way (COPD, 2013). Progressive means that is gradually gets worse over time. It is a combination of chronic bronchitis and emphysema (Causes,2014). Chronic bronchitis is inflammation of the bronchioles, which causes mucus build up (Davis,2016). Emphysema is when the air sacs get enlarged (Smoking, 2016). Since the disease does not have a cure yet it is important to know pathology (path of disease), epidemiology (who is effected in a population), ethology (who is effected genetically), manifestation (symptoms), treatment, and outcome. First step preventing COPD is to know how it affects the body and the path taken; this is called the pathology. In normal, healthy breathing a person breathes in air that is moves through the bronchial tubes to the bronchioles. At the end of the bronchioles there are air sacs called alveoli. The alveoli are elastic air sacs that control the gas exchange of oxygen and carbon dioxide to the body (Smoking, 2016). The alveoli consist of elastic tissue so when a person breaths in the the alveoli can expand and when the carbon dioxide is released it can deflate and return to it’s normal size.
