Atrophic rhinitis in pigs primarily damages which nasal structures?

Explanation:
Atrophic rhinitis primarily damages the nasal turbinates—the scroll-like bony shelves inside the nasal cavity that greatly increase surface area for the mucosal lining to filter, humidify, and warm inspired air. When these structures atrophy, the nasal surface area is reduced, airflow is altered, and the snout may become shortened due to structural loss. The lungs, larynx, and sinuses are not the initial targets of this disease, so the turbinate damage best explains the pathology observed.
