b. To filter out dust and bacteria

c. To filter coarse particles from inhaled air

d. To facilitate the movement of air through the naresANS>>: C

The nasal hairs, or cilia, filter the coarsest matter from inhaled air, whereas the

warms the

inhaled air. The rich blood supply of the nasal mucosa warms the inhaled air, not
the ciliated

mucous membrane. The mucous blanket, not the cilia, filters out dust and
bacteria. The cilia in

the nose do not facilitate the movement of air through the nares. Instead, the

The projections in the nasal cavity that increases the surface area are called
turbinates. The

lateral walls of each nasal cavity contain three parallel bony projections: the
superior, middle,

and inferior turbinates. These increase the surface area, making more blood
vessels and

mucous membrane available to warm, humidify, and filter the inhaled air. A
meatus is the

passageway or canal underlying each turbinate that collects drainage. The septum
is what

divides the nasal cavity into two slitlike air passages. The Kiesselbach plexus is a
rich

vascular network in the anterior part of the septum.
