Document Summary

503 516: air-conducting portion: nose pharynx larynx trachea bronchi (1 , 2 & 3 ) . Bronchioles terminal bronchioles (passage of air via nose: respiratory portion: respiratory bronchioles & alveoli. Inspiration & expiration (physical movement of air in and out of lungs. Protection of respiratory surfaces (dehydration, temp change and invading pathogens) Gas exchange (o2 in and co2 out) Respiratory mucosa: tract = lined by this: resp. Nasal vestibule = lined by epi and is space enclosed w/in flexible tissues. Cavity = q-shaped w/ 6 sides (ant & post wall, medial & lateral wall, roof & floor) Ant = external nares (nostrils); post = internal nares. Lateral = nasal conchae (2 superior, 2 middle & 2 inferior) is a bony shelf-like projection covered by mucosa. Medial = nasal septum (ant = hyaline cartilage, post = ethmoid (_|_ plate) & vomer)
