cov ntaub so ntswg epithelial yog dav thoob plaws hauv lub cev. Lawv tsim npog tag nrho lub cev qhov chaw, kab lub cev kab noj hniav thiab cov kabmob hollow, thiab yog cov ntaub so ntswg loj hauv qog. Lawv ua ntau yam haujlwm uas suav nrog kev tiv thaiv, zais cia, nqus, tshem tawm, pom, nthuav tawm, thiab txais kev hnov lus.
Cov ntaub so ntswg epithelial pom nyob qhov twg?
→ Cov ntaub so ntswg epithelial yog nruj nreem ntim thiab tsim ib daim ntawv txuas ntxiv. → daim tawv nqaij, hauv ob sab phlu ntawm lub qhov ncauj, hauv ob sab ntawm cov hlab ntsha, lub ntsws alveoli thiab lub raum tubulesyog tag nrho cov ntaub so ntswg epithelial.
Yuav ua li cas lub cev muaj cov ntaub so ntswg epithelial?
Epithelial cov ntaub so ntswg npog sab nraud ntawm lub cev thiab kab hauv nruab nrog cev, hlab ntsha(ntshav thiab lymph), thiab kab noj hniav. Epithelial hlwb tsim cov txheej nyias nyias ntawm cov hlwb hu ua endothelium, uas yog sib txuas nrog cov ntaub so ntswg sab hauv ntawm lub cev xws li lub hlwb, ntsws, tawv nqaij, thiab lub plawv.
