This medical exhibit contrasts normal nasal passage anatomy with allergic rhinitis in a series of four illustrations. The first two graphics depict cut-away views of the normal nasal area with labels for nasal septum, superior, middle and inferior nasal conchae, pharyngeal orifice of the auditory, (eustachian) tube, and the maxillary sinus. The next two graphics display the same views and labels, this time with captions indicating the inflammation of the nasal mucosa with exudate in the airway.
