Where are the inferior nasal conchae located?
inferiorly to the middle conchae
What are the middle and superior nasal conchae formed from?
grooves of the ethmoid bone
What are the purposes of the nasal conchae?
swirl air that is breathed through the nasal passages
warm and humidify the air before it enters lower respiratory system
