Question

Quizplus · Accepted Answer

Constriction of smooth muscle in bronchioles is a classic symptom of asthma, which is caused by inflammation and hyper-reactivity of the airways. Emphysema is characterized by damage and destruction of lung tissue, leading to a loss of elasticity and reduced airflow. Pulmonary edema results from an accumulation of fluid in the lungs, which can make breathing difficult but is not directly related to bronchoconstriction. Pneumothorax occurs when air collects in the space between the lung and chest wall, causing the lung to collapse and also not related to bronchoconstriction.
