|
|
|
alveolar sac and alveoli
|
sim squamous Type I and II pneumcytes, elastic and reticular fibers in interalveolar septum w/ capillary netowrk and alveolar pores
|
|
|
vibressae
|
thick short hairs that filer glands in vestibule
|
|
|
swell bodies
|
large venous plexus in lamina propria, engorged by blood to avoid desiccation
|
|
|
brush cells
|
columnar w/ numeous microvilli, afferent nerve ending on basal, for SENSORY receptor
|
|
|
basal or short cells
|
small rounded, lie on BL, do not extend, stem cell, for REGENERATION
|
|
|
small granule/kulchitsky cells

3%, belong to diffused neuroendocrine system
|
|
|
what cells make up olfactory epithelium?
|
supporting, basal, olfactory
|
|
|
supporting cells?
|
broad, cylindrical apex, narrow base, microvill, for yellow pigment for color
|
|
|
olfactory cells
|
b/w basal and supporting cells, bipoolar neurons which lie below nucei of supporting, apexes possess elevated and dilated areas which nonmotile cilia respond to odoriferous substances
|
|
|
bowmans gland
|
found b/w cells in olfactory epi, in lamina propria, creates fluid environment around olfactory cilia that may clear cilia
|
|
|
epiglottis
|
lingual side- str sqaua, laryngeal side- respi w/ mixed and serous glands
|
|
|
trachealis ms
|
regulates diameter of lumen trachea
|
|
|
fibroelastic ligament
|
prevents over diestention of trachea
|
|
|
bronchus
|
similar to trachea w/ irreg hyaline cart, lymoid tissue underneath epithelium called BALT classifised under MALT, have mast cell in bronchial wall for allergic rxn
|
|
|
clara cells
|
devoid of cilia, contain secretory granules, proteins which protect bronchial epi from oxidative pollutants and inflammation
|
|
|
neuroendocrine cells
|
in bronchiones- chemoreceptors, react to changes in gas composition w/in airway, also reparative process after inhugry
|
|
|
deep netowrk
|
enter interlobular septum then follow bronchial segments then HILAR nodes
|
|
|
superficial network
|
in visceral pleaura, follow entire elngth pleura, pentrate lung tissue via interlobular septum then drain into HILAR
|
|
|
dust cells
|
alveolar macrophages, granular when engluf particle
|
|
|
alveolus
|
functional unit of lungs, gas exchange, sac like evaingations, lined by squamous alveolar cells and great alveolar cells (type 1 and 2)
|
|
|
interstitum
|
where capillares, CT, cells and blood air barrier found
|
|
|
type 1
|
squamous alveolar cell, thin 97%
|
|
|
type 2
|
larged, clumped, laimnar bodies make surfactant-help prevent collapse of lungs during expiration
