Question
COPD Chronic obstructive pulmonary disease (COPD) is caused by a long-term obstruction of airflow, which decreases pulmonary ventilation. Two major COPDs are emphysema and chronic bronchitis. For each COPD, indicate which variables would be increased or decreased. Force generation of | Mucus production Length of respiratoryLung elasticity Size of alveoli respiratory muscles muscles Number of respiratory cilia Number of alveli Thoracic volume Moblity of ciliaNumber of bronchial mucosa cells Emphysema Chronic Bronchitis Increased Increased Decreased Decreased Brand XPicturesExplanation / Answer
Emphysema
1. Increased parameters
Mucous, thorax volume, length of respiratory muscles, force generation of respiratory muscles
2. Decreased parameters.
Size of alveoli, elasticity, cilia, number of alveoli, motility of cilia.
Chronic bronchitis
1. Increased parameters
Force generated by muscles, length of muscles, mucous production,number of bronchial mucosa cells.
2. Decreased parameters
Number of respiratory cilia, motility of cilia.
