respiratory system

Question Answer
what are the 2 main anatomical portions of the respiratory systemupper and lower respiratory system
what makes up the upper respiratory systemnasal cavities, sinuses, nasopharynx
what make sup the lower respiratory tractlarynx, trachea, terminal broncioles, respiratory bronchioles, alveolar ducts, sacs, and alveoli
what are the 2 functional divisions of the respiratory systemthe conduction portion and the respiratory portion
what makes up the conduction portionnasal cavities, nasopharynx, larynx, trachea, bronchi, terminal bronchioles
what is the function of the conduction portion of the respiratory systemwarm, humidfy, and filter air
what makes up the respiratory portion of the respiratory systemrepiratory bronchioles, alveolar ducts, sacs and alveoli
what is the function of the respiratory portion of the respiroatory systemgaseous exchange
list the portions of the respiratory tract from start to finishpharynx, larynx, trachea, primary bronchi, secondary, tertiary bronchi, terminal bronchus, respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli
where do primary bronchi goto R/L lung
where do secondary bronchi goto lobes of the lungs
where do the tertiary bronchi goto the bronchiopulmonary segments
what is the only portion of the body with neuroepitheliumthe cribriform plate on the upper border of the nasal cavity
what forms the lateral wall of nasal cavitythe superior, middle and inferior nasal conchae
what type of cells line the nasal chonchaeciliated pseudostratified epithelium with GOBLET CELLS
what portion of the nasal septum’s lack the pseudostratified epitheliumthe superior, because it contains the neuroepithelium
what is the lamina propriathe connective layer under the epithelium in the nasal cavity and respiratory tract
what are the contents of the lamina propria in the nasal cavityblood vessels, serous and mucous glands
what line the paranasal sinusesbony air filled cavities lined by lamina propria and epithelium
where is the olfactory portion of the nasal cavityon the superior nasal chonchae and upper portion of the nasal septum
what is the lining of the olfactory portions of the nasal cavityneuroepithelium, which is a pseudostratified epithelium
what type of neurons ar in the neuroepitheliumbipolar neurons
what is the lining of portions of the pharynx open to abrasionnonkeratinized stratified squamous epithelium
what is the lining of areas of the pharynx not meant ofr abrasionpseudostratified ciliated epithelium
what is the makeup of the lamina propria in the pharynxconnective tissue
what is the function of the larynxair passage and speech generation
what is the skeleton of the larynx made ofhyalne cartilage
what covers the laryngeal enterance while swallowingthe epiglottis
what is the composition of the epiglottiselastic cartilage
what is the structure responsible for generation of sound in the larynxthe vocaialis muscle and the vocal folds
what are the two different types of lining of the larynxpseudostratified ciliated epithelium and in abrasive areas, stratified non keratinized squamous epithelium
what is the distal division of the larynx, what structures come nextthe primary bronchi
what is the function of the tracheaa conduit for air
what is the composition of the tracheafibroelastic tissue
what are the 3 layers of the trachea wallsmucosa, submucosa, cartilage support
what is the composition of the mucosa layer of the tracheapseudostratified ciliated epithelium with ciliated columnar cells, goblets, serous, DNES, stem and basal cells
what are DNES cellsneuroendocrine cells in the pseudostratified epithelium of the trachea
what seperates the mucosa from the submucosa in the tracheaan elastic lamina
what is the composition of the submucosafibroelastic connective tissue with serous and mucous glands, diffuse lymphatic tissue and large venous sinouses
what connects the ends of the C cartilage in the tracheatrachealis muscle (smooth)
what connects adjacent rings in the tracheafibroelastic tissue
what cavity contains the lungsthe pleural cavity
how many primary bronchi are there2, 1 right and 1 left
how many secondary bronchi are there3 right 2 left
how many tertiary bronchi are there10 right 8 left
what are the pleural layers of the thoracic cavityvisceral and parietal
where are the two pleura of the lungs continuousat the hilum of the lugns
what are the three layers of the primary bronchimucosa, submucosa, and cartilage
what is the cellular composition of the mucosa layer of the primary bronchipseudostratified ciliated epithelium
what is the difference between the pseudostratified epithelium in the primary bronchi and the trachealess goblet cells in the primary bronchi
what is the lamina propria of the primary bronchidense fibroelastic connective tissue with elastic fibers, diffues lymphatic tissue , serous, mucous glands, blood vessels
what does the mucous layer of the primary bronchus have that the trachea does not havediscontinuous muscularis mucosa
submucosa of primary bronchifibroelastic connective tissue with fewer glands, and diffuse lymphatic tissue
what is the cartilage support of the primary bronchiC rings connected with smooth muscle
secondary bronchi layersmucosa, submucosa, cartilage
mucosa of secondary bronchiciliated pseudostratified epi to ciliated simple columnar epi
what is the difference btwn the primary bronchi mucosa and the secondary bronchi mucosathinner lamina propria with more elastic fibers… diffuse lymph tissue, serous and mucous glands, vessels CONTINCUOuS MUSCULARIS MUCOSA
submucosa of seconday bronchiolesfibroelastic tissue, sparse glands, lymphatic tissue
cartilage layer of secondary bronchiflattened plates of hyaline cartilage
what is emphysemaloss of the elasticity of the lungs
memorize
TERTIARY BRONCHI
Question Answer
mucosaciliated columnar cells fewer goblet cells, thinner lamina propria, ore elastic fibers, diffues elastic tissue, serous mucous glands, blood vessels, COMPLETE MUSCULAARIS MUCOSA
submucosafibroelastic connective tissue, fewer glands, lymphatic tissue
cartilagefew hyaline cartilage plates like islands
memorize
TERMINAL BRONCHIOLES
Question Answer
cartilage1st layer without cartilage support
lumen shape of the terminal bronchiolesstar shaed
mucosaciliated columnar to ciliated cuboidal, goblet cells replaced by clara cells, DNES cells, thinner lamina propria, NO glands, complete muscularis mucosa
submucosaloos connective tissue without glands
memorize
RESP BRONCHIOLES
Question Answer
gaseous exchange1st layer where exchange occurs
mucosaciliate cuboidal with clara cells, thin lamina propria, no muscularis mucosa, occasional smooth muscle bundles
memorize
ALVEOLAR DUCTS
Question Answer
mucosalow cuboidal epithelium, little lamina propria, occasional smooth muscle
memorize
ALVEOLI
Question Answer
alveolar wall compositionsurface epithelium, supporting tissue, continuous capilarries
composition of surface epitheliumtype I and II alveolar cells
what are type I alveolar cellssquamous cells that are part of the gas diffusion barrier
