mucous membranes, lots of blood vessels, cilia and turbinate bones
what is the purpose of nasal mucous membranes
to help warm the air
what does cilia do in the nasal cavity
helps to filter out the air
what is the purpose of the turbinate bones in the nasal cavity

where does the trachea extend to and from
from the larynx to the bronchi
how many bronchi are there

what are the alveolar ducts
final passage tube into alveoli
what are alveoli

whats teh pleur
