Defense Mechanisms against Upper Respiratory Infections • Hair lining nasal cavity expel the incoming pathogens. • Mucous lining the respiratory tract traps intruders. • Angle at the junction of posterior nose to pharynx impinge large particles at the back of throat. • Cilliated cells trap and transport the pathogens from respiratory tract to pharynx from where they are swallowed into the stomach and destroyed.
