nostrils/nares: end at vocal cords; heating, cooling, filter humidify, oflaction, phonations, ventilation
turbinates: make incoming air current more turbulant, bringing more air in contact w/ mucous membranes for warming and humidifying, adding 650-1000 mls of H2O each day to moisten air to 80% humidity
allergic rhinitis: occurs when allergens trigger nasal mucosa to secrete excessive mucous causing the running nose
-
pseudostratified ciliated columnar cells: cells in epithelial lining of airways of nose and resp system
gel layer: top layer that is more viscous and sticky, traps small particles and dust
