n ib epithelial ntawm tes uas yog zoo li tus kem; qee tus muaj cilia. Lub ntsiab lus: columnar epithelial ntawm tes Hom: spongioblast. ib yam ntawm ntau yam columnar epithelial hlwb nyob rau hauv lub hauv paus paj hlwb uas loj hlob mus rau hauv neuroglia. Hom: epithelial ntawm tes . ib qho uas tau ntim zoo hlwb tsim lub epithelium cov ntaub so ntswg.
Hais txog qhov no, dab tsi yog txoj haujlwm ntawm columnar epithelial hlwb?
Piav: Yooj yim columnar epithelia nrog microvilli secrete digestive enzymes thiab nqus cov zaub mov. Yooj yim columnar epithelia nrog kev pab cilia hauv kev txav ntawm cov hnoos qeev thiab kev ua me nyuam hlwb . Columnar epithelial hlwb yog cov kab mob epithelial nws qhov siab yog tsawg kawg plaub zaug lawv qhov dav.
Ib tug kuj yuav nug, dab tsi yog txhais los ntawm columnar epithelium? Txhais . npe, plural: columnar epithelia . Ib epithelial cov ntaub so ntswg muaj columnar epithelial cell, nrog los yog tsis muaj cilia, thiab feem ntau koom nrog hauv secretory, absorptive, los yog excretory functions. Ntxiv. Cov epithelial ntaub so ntswg (tseem hu ua epithelium cov ntaub so ntswg ) yog ib qho ntawm ntau hom tsiaj cov ntaub so ntswg.
Raws li, qhov twg pom cov cell columnar?
Yooj yim columnar epithelia muaj nyob hauv plab , hnyuv me , txoj hnyuv loj , lub qhov quav, cov hlab ntsha hauv plab, endometrium, thiab ua pa bronchioles. Hauv qhov tseem ceeb, lawv pom nyob hauv ib feem ntawm txoj kev ua pa, plab zom mov thiab cov kab mob me me uas cov tshuab ua kom puas tsawg, tab sis kev zais cia thiab kev nqus yog qhov tseem ceeb.
Vim li cas thiaj yooj yim columnar hauv plab?
Yooj yim columnar epithelium muaj ib txheej ntawm cov hlwb uas siab tshaj qhov dav. Hom epithelia no kab cov hnyuv me uas nws nqus cov as-ham los ntawm lumen ntawm txoj hnyuv. Yooj yim columnar epithelia kuj muaj nyob rau hauv lub plab qhov twg nws secretes acid, digestive enzymes thiab mucous.

Cov hlwb uas tsim myelin, tiv thaiv, txhawb nqa, thiab tswj kev sib npaug hauv koj lub paj hlwb hu ua glial cells. Lawv kuj tseem raug hu ua neuroglia thiab txawm tias yooj yim dua glia. Hauv cov lus ntxaws ntxaws, neuroglia yog cov hlwb hauv koj lub paj hlwb uas tsis yog neurons

T hlwb yog li ntawd hu ua vim lawv feem ntau tsim nyob rau hauv lub thymus. Raws li cov npe hais tias pab T hlwb 'pab' lwm lub hlwb ntawm lub cev tiv thaiv kab mob, thaum cytotoxic T hlwb tua cov kab mob kis kab mob thiab qog. Tsis zoo li cov tshuaj tiv thaiv kab mob, TCR tsis tuaj yeem khi cov tshuaj tiv thaiv ncaj qha

T cells koom nrog hauv kev tiv thaiv kab mob ntawm tes, qhov B hlwb feem ntau yog lub luag haujlwm rau kev tiv thaiv kev dag ntxias (hais txog cov tshuaj tiv thaiv). Kev ua haujlwm ntawm T hlwb thiab B hlwb yog kom paub txog cov 'tsis yog tus kheej' antigens, thaum lub sijhawm ua haujlwm hu ua antigen nthuav qhia
