Wheezes are high-pitched, continuous sounds that occur when air flows through narrowed airways. In conditions like asthma and COPD (Chronic Obstructive Pulmonary Disease), inflammation, bronchospasm, or excess mucus can contribute to the narrowing of the airways, leading to these characteristic wheezing sounds during expiration or expiration. The presence of wheezing indicates that the airways are significantly constricted, making it more challenging for air to pass through, which is a hallmark of these respiratory disorders.

While crackles, rhonchi, and pleural friction rubs indicate different types of respiratory issues, they do not specifically reflect the narrowing of airways in the same way that wheezes do. Crackles are typically associated with fluid in the airways (such as in pneumonia), rhonchi are often related to mucus obstruction in the larger airways, and pleural friction rubs indicate inflammation of the pleurae rather than airway constriction. Thus, the associated wheezing sound distinctly points to the challenges faced in asthma and COPD, making it the correct choice.
