Which disorder involves inflammation of the nasal passages?

Rhinitis is characterized by inflammation of the nasal passages, which can occur due to various triggers such as allergens, infections, or irritants. This inflammation leads to symptoms like nasal congestion, runny nose, sneezing, and itching. In allergic rhinitis specifically, allergens like pollen or dust can provoke an immune response that exacerbates these symptoms.

Understanding the nature of rhinitis is important in differentiating it from other respiratory conditions. For instance, while rhinorrhea refers to an excessive discharge from the nose and can be a symptom of rhinitis, it does not specifically denote the inflammation itself. Sinusitis involves inflammation of the sinuses, which are located around the nasal passages, rather than the passages themselves. Bronchitis, on the other hand, pertains to inflammation in the bronchial tubes, which affects the respiratory system differently, primarily causing coughing and phlegm production rather than the nasal symptoms seen in rhinitis.

Thus, rhinitis is the correct answer as it directly refers to the inflammation of the nasal passages, making it the most accurate term among the provided options.
