*In addition to [[Special Senses - Olfactory - Anatomy & Physiology|Olfaction,]] the function of the nasal cavity is to modify the incoming air before is is transported further down the respiratory tract.

*Air is warmed as it passes over the highly vascularised mucosal surfaces of the conchae, humidified by the evaporation from nasal secretion and cleaned as it contacts the secretion from mucus glands within the nasal cavity. The mucus secreted from the glands traps particles and cilia transport them down to the pharynx for swallowing.
