Bronchitis is defined primarily by the inflammation of the bronchi, the major air passages from the trachea to the lungs. This condition often involves irritation and swelling of the airways, which can lead to recurrent respiratory infections. The term encapsulates both acute episodes and chronic issues that can lead to persistent symptoms.

The correct definition emphasizes not only the inflammation itself but also the tendency for recurrent infections that can result from this inflammation, making it a significant aspect of bronchitis. The presence of these recurrent infections indicates a more complex and chronic state of the respiratory system rather than a singular event. This understanding is crucial in recognizing the severity and implications of bronchitis for patient care and management.

Other definitions may partially describe bronchitis, such as the swelling of airways or the production of mucus, but they do not encompass the full scope of the condition, particularly the aspect of recurrent infections which highlights the chronic nature of the disease. Thickening of bronchioles is a potential physiological response but does not align with the comprehensive definition of bronchitis, especially in regard to its infectious complications.
