Stridor is primarily associated with which part of the respiratory system?

Stridor is a high-pitched, wheezing sound that occurs when there is an obstruction or narrowing in the upper airways. This sound is typically heard more prominently during inhalation and is indicative of a problem in the larynx, trachea, or other structures located in the upper respiratory tract. Given its association with these structures, it makes sense that the correct answer identifies the upper airways as the primary location linked to stridor.

In comparison, the lower airways, alveoli, and bronchioles are associated with different types of respiratory sounds and issues. For instance, conditions affecting the lower airways might lead to wheezing rather than stridor, emphasizing the importance of correct anatomical localization when addressing respiratory symptoms.
