What is the role of mucus in rhinitis?

• A. Provides Nutrients
• B. Traps Pathogens
• C. Facilitates Blood Flow
• D. Neutralizes Acids

Answer: (B)

Mucus plays a crucial role in the respiratory system, particularly in conditions such as rhinitis. One of its primary functions is to trap pathogens, including bacteria, viruses, and dust particles that may enter the nasal passages. This protective mechanism helps to prevent these foreign invaders from reaching the delicate tissues of the respiratory tract, thereby reducing the risk of infection and inflammation. The sticky nature of mucus allows it to effectively capture these harmful substances, which can then be cleared away through actions like sneezing or swallowing. In rhinitis, which involves inflammation of the nasal mucosa, the production of mucus often increases as the body responds to allergens or irritants. This excessive mucus can lead to symptoms such as a runny nose or congestion, but its critical function in trapping pathogens remains essential for maintaining respiratory health.
