Question: 1 / 400

What does the term "bronchoconstriction" refer to?

Narrowing of the airways

Bronchoconstriction refers to the narrowing of the airways, particularly the bronchi and bronchioles, which can occur due to various physiological mechanisms, including muscle contraction around the airways and inflammation. This narrowing can lead to increased airway resistance, making it more difficult for air to flow in and out of the lungs. Conditions such as asthma or allergic reactions often involve bronchoconstriction, where the smooth muscle surrounding the airways contracts, further limiting airflow and causing symptoms such as wheezing, coughing, and shortness of breath. Understanding bronchoconstriction is crucial for respiratory therapists, as they frequently encounter patients with airway compromise and need to implement appropriate therapies, such as bronchodilators, to relieve this constriction and improve respiratory function.
