”1. Name two functions of the nasal cavity mucosa.”
It traps debris from the air. It humidifies (and warms) the air being brought into the respiratory
system.

To protect and support the trachea, allowing it to stay open for the movement of air.
”3. Describe the path a molecule of oxygen takes to get to body tissue, starting with the nares. ”
Nares, meatus (superior, middle, or inferior), nasopharynx, laryngopharynx, larynx, trachea,
bronchi, lobar bronchi, segmental bronchi, bronchioles, terminal bronchioles, respiratory
bronchioles, alveolar ducts, alveolar sacs, alveoli, interstitial space, pulmonary capillaries (now

Respiratory Image Description of Visible Structure(s)
The cilia are small in comparison to the other
structures. Closest to the lumen is the cilia.
Trachea Moving away, there are goblet cells,
columnar cells, a basement membrane, and
connective tissue of the lamina propria.
Multiple openings of bronchi, bronchioles,
alveolar sacs, and alveoli are visible within
Lung the cross-section. Upon further
magnification, the thinness of the simple
squamous epithelium of the alveoli is visible.
