Flashcards in Respiratory system Deck (56)
Oxygen and CO2 exchange
and Conditioning of air are all functions of what?
What is the respiratory portion of the respiratory system
O2 and CO2 exchange
What is the conducting portion of the respiratory system
And conditioning of air
True or false; along with warming and moistening the air, conditioning of the air refers to filtration of large to small particulate
True or false; the conduction portion of the respiratory system transport air to the respiratory portion
The surface epithelium of the nasal vestibule is made up of what?
keratinized stratified squamous epithelium
What kind of glands would you find in the vestibule of the nasal cavity
sweat and sebaceous
What kind of cartilage makes up the vestibule of the nasal cavity
True or false; the mucociliary apparatus in the respiratory region of the nose filters medium size particulate
Where would you find seromucus glands in the nose?
The mucus portion of the serumucus glands of the nose functions to
The serous products produced by the seromucus glands of the nose act as a...
small particulate filter : Lysozyme (antibacterial) Interferons (antiviral) Cytokines (stimulate defense cells)
True or false; along with the seromucus glands, in the lamina propria of the nose you would expect to find a cavernous plexus with many large venules typically filled with blood
What are the 3 functions of the cavernous plexus in the lamina propria of the nose
Provide defense (inflammation within lamina propria - stuffy nose - also increased blood -> increased O2 -> stimulate seromucus secretion -> runny nose)
True or false; the Paranasal sinuses are found in the ethmoid, sphenoid, frontal and maxilla bones; and connect to nasal cavity
true - connects through sinal ostia
Do the paranasal sinuses have a lamina propria?
yes; but is thin - has seromucus glands and quite vascular
What possible problem can arise due to small ostia connecting paranasal sinuses
inflammation can cause a blockage and subsequent sinus infection
What are the 3 subdivisions of the pharynx
What kind of cells cover the surface epithelium of the mucosa of the nasopharynx
Respiratory epithelium - Mucociliary clearance
What kind of cells cover the surface epithelium of the mucosa of the oropharynx and Laryngopharynx
stratified squamous epithelium
True or false; the whole respiratory system has no muscularis mucosa
What would you expect to find in the lamina propria (loose ct.) of the nasopharynx
Pharyngeal and tubal tonsils
What would you expect to find in the lamina propria (loose ct.) of the Oropharynx
Lingual and palatine tonsils
Would you expect to see any tonsils in the lamina propria (loose ct.) of the Laryngopharynx
True or false; the submucosa of the pharynx = Pharyngobasilar fascia
true; Collagen in periosteum of basilar portion of occiput blends into wall of pharynx
What function does the submucosa of the pharynx (Pharyngobasilar fascia) have?
Adds support to 90 degree turn of head
What kind of muscle makes up the muscularis externa of pharynx? What is unique about the fiber arrangement?
All skeletal muscle
Unique because reverse pattern - Longitudinal inner and Circular outer (this arrangement also occurs in uterus)
True or false; the Adventitia of the pharynx = Buccopharyngeal Fascia
True or false; the Epimysium of buccinator muscle blends into the adventitia of pharynx (Buccopharyngeal fascia)
