___ lines the conducting portion of the respiratory tract	respiratory mucosa
a pseudo stratified ciliated columnar epithelium with numerous mucous cells lines the ____, ___, ____, bronchi and large bronchi	nasal cavity, superior portion of pharynx, trachea
the flow of mucus is often described as a ____	mucus escalator
____ is the underlying layer of areolar tissue that supports the respiratory epithelium	lamina propria
respiratory mucosa, with mucous cells and mucus escalator, lines the ____ and the ____	nasal cavity, superior portion of the pharynx
stratified squamous epithelium lines the _____, protecting the epithelium from abrasion and chemical attack	inferior portions of the pharynx
a typical respiratory mucosa lines the conducting portion of the ____	lower reparatory tract
in the finer bronchioles, the epithelium becomes ___	cuboidal
gas exchange surfaces consist of _____	simple squamous epithelium
Which type of epithelium lines the inferior portions of the pharynx?	stratified squamous epithelium
to pass from the external nares to the internal nares, air flows between adjacent conchae though the _____	superior middle and inferior meatuses
Divides the nasal cavity into left and right portions, formed by the fusion of perpendicular plate of the ethmoid and vomer	nasal septum

the ___ conducts air toward the lungs	trachea or windpipe
the ____ is the space contained within the flexible tissues of the nose. Its epithelium contains hairs that trap large airborne particles	nasal vestibule
inhaled air leaves the pharynx and enters the larynx though a narrow opening called ____	glottis
___ cartilaginous structure that surrounds and protects the glottis	larynx
lamina propria contains an extensive network of large and highly expandable ___ that can release heat like a radiator. It can cool and dry air in nasal cavity	veins
___ folds over glottis during swallowing, preventing liquids and food from entering respiratory tract	epiglottis
the prominent anterior surface of the thyroid cartilage, which you can easily feel and see is called __	laryngeal prominence
___ has expanded posterior portion that provides support and protects the glottis	cricoid cartilage
Which structure(s) function(s) in the opening and closing of the glottis and the production of sound?	corniculate and arytenoid cartilages
Which laryngeal cartilage(s) is/are small, long, and curved, and lie(s) within folds of tissue that extend between the lateral surface of each arytenoid cartilage and the epiglottis?	cuneiform cartilages
when the glottis is open air passing though vibrates the	vocal folds
___ folds help prevent foreign objects from entering the glottis	vestibular folds
sound production at the larynx is called ____. However clear speech requires ____ which is the modification of sounds by other structures	phonation, articulation
after entering the lung the bronchus divides to form ____, which divides to form ____	secondary bronchi, tertiary bronchi
each tertiary bronchus branches several times, giving rise to multiple ___	bronchioles
___ stiffen tracheal walls and prevent its collapse or over expansion as pressure change	tracheal cartilages
contraction of the ____ reduces the diameter of the trachea, increasing resistance to airflow	trachealis muscle
most foreign objects that enter the trachea find their way into the ___	right bronchus
Each terminal bronchiole supplies which singular structure?	pulmonary lobule
___ is a meshwork of dense connective tissue that fixes the positions of the bronchi, major nerves, blood vessels, and lymphatics	root of the lung
each ____ bronchus supplies air to the bronchopulmonary segment	tertiary bronchus
the right lung is divided by the ____ and ___ into three lobes: the superior, middle and inferior lobes	horizontal, oblique fissures
left lung is divided by the ____ into only two lobes: the superior and inferior lobes	oblique fissure
____ accommodates the pericardial cavity, which sits to the left of the midline	cardiac notch
the ___ of the lung is a groove that allows passage of the primary bronchi, pulmonary vessels, nerves, and lymphatics	hilum
the conducting and respiratory portions of the respiratory tract are continuous and end in air sacs called ____	alveoli
each terminal bronchiole supplies a single __	pulmonary lobule
the alveolar epithelium is primarily a ____ epithelium	simple squamous
