Cov ntaub so ntswg epithelial npog sab nraum lub lub cev thiab kab mob, cov hlab ntsha (ntshav thiab lymph), thiab kab noj hniav. Epithelial cov hlwb tsim cov txheej nyias ntawm cov hlwb hu ua endothelium, uas txuas nrog rau sab hauv cov ntaub so ntswg kab hauv nruab nrog cev xws li lub paj hlwb, lub ntsws, tawv nqaij, thiab lub plawv.
Kuj nug, cov ntaub so ntswg epithelial nyob qhov twg hauv lub cev?
Cov ntaub so ntswg epithelial kab sab nrauv ntawm lub cev thiab cov hlab ntshav thoob plaws lub cev , nrog rau qhov chaw sab hauv ntawm cov kab noj hniav hauv ntau lub cev. Ib qho piv txwv yog epidermis, txheej sab nrauv ntawm daim tawv nqaij.
Qhov thib ob, hom ntaub so ntswg epithelial pom nyob rau ntawm daim tawv nqaij? Stratified squamous epithelium
