Which term describes an involuntary contraction of the muscular lining of the bronchi?

Bronchospasm describes the involuntary contraction of the smooth muscle lining the bronchi, leading to a narrowing of the airways. This condition is often associated with various respiratory issues, including asthma and allergic reactions, and results in symptoms such as wheezing, coughing, and difficulty breathing. Understanding bronchospasm is crucial in medical terminology as it highlights how the body responds to irritants or allergens and emphasizes the importance of the bronchial muscles in respiratory health.

Other terms, like bronchitis, refer to the inflammation of the bronchial tubes, while bronchiectasis involves the permanent dilation of the bronchi due to damage or infection. Bronchorrhea signifies an excessive discharge of mucus from the bronchi, which, although it can accompany bronchospasm, does not specifically describe the involuntary muscle contractions involved. Hence, bronchospasm is the most accurate term for this involuntary contraction.
