Question

Quizplus · Accepted Answer

Emphysema is a chronic, progressive condition characterized by shortness of breath and an inability to tolerate physical exertion. The underlying problem in emphysema is that the lung tissue has lost its elasticity. Asthma is a chronic inflammatory condition that causes narrowing of the airways, but it is not necessarily characterized by a loss of lung tissue elasticity. Bronchitis is an inflammation of the bronchial tubes that can cause cough and mucus production, but it is not necessarily characterized by a loss of lung tissue elasticity. Respiratory distress syndrome is a condition that most commonly affects premature infants and is characterized by insufficient surfactant production in the lungs. Lung cancer is a malignant growth in the lungs that can cause shortness of breath, but it is not necessarily characterized by a loss of lung tissue elasticity.
