Lawv yog pom nyob rau hauv lub trachea, bronchi, thiab loj bronchioles nyob rau hauv lub ua pa ib ntsuj av tau, cov hnyuv me, cov hnyuv loj, thiab conjunctiva nyob rau hauv daim tawv muag sab sauv. Nyob rau hauv lub conjunctiva goblet cells yog ib qhov chaw ntawm mucin hauv kua muag thiab lawv kuj zais ntau hom mucins mus rau qhov muag qhov muag.
Hais txog qhov no, goblet cells nyob qhov twg thiab lawv txoj haujlwm yog dab tsi?
Hauv cov cov hnyuv me thiab loj, goblet hlwb Nws yog dispersed ntawm enterocytes. Lawv lub ntsiab muaj nuj nqi nov yog tsim cov hnoos qeev uas tiv thaiv thiab ua kom lub cev ntub cov nto ntawm cov cov hnyuv.
Ib yam li ntawd, cov qog mucous nyob qhov twg? Cov qog ua kua nyob rau ntawm qhov chaw thiab hauv lub caj dab ntawm cov qog nqaij hlav (GGs).
Ua kom pom qhov no, qhov mucosa twg muaj cov qe ntshav?
Goblet hlwb yog columnar basophilic hlwb tawg nyob rau hauv epithelia ntawm lub conjunctiva, txoj hnyuv , thiab kab mob ua pa. Hauv cov hnyuv mucosa, lawv yog cov hlwb tshwj xeeb uas tsim cov hnyuv mucin, lub siab-molecular-hnyav glycoprotein uas muaj cov tub ntxhais cov protein thiab ntau cov mucin-hom qab zib saw.
Puas yog cov kab mob goblet cells mucous cells?
Epithelial hlwb uas yog tshwj xeeb rau secrete hnoos qeev hu ua cov hnoos qeev . Goblet hlwb , uas sawv ib leeg tsis pub dhau lub epithelium saum npoo av, yog tus yam ntxwv tshwj xeeb ntawm txoj hnyuv (nrog rau txoj kev ua pa thiab cov poj niam deev me nyuam).

Tus neeg nce mucus nyob qhov twg?
Cov mucociliary escalator muaj nyob hauv cov hlab ntsws, bronchi, thiab bronchioles, uas yog ib feem ntawm thaj tsam kev coj ua
T cells thiab B cells ua haujlwm li cas?
Tom qab ntawd koj lub cev tuaj yeem tsim cov riam phom zoo tshaj plaws tiv thaiv cov neeg tawm tsam, uas tuaj yeem yog kab mob, kab mob lossis kab mob parasites. Lwm hom T-cells paub thiab tua cov kab mob uas muaj kab mob ncaj qha. Qee qhov pab B-cells ua cov tshuaj tiv thaiv kab mob, uas nthuav dav thiab khi rau antigens. T-cell (txiv kab ntxwv) tua kab mob qog noj ntshav (mauve)
Lub qhov hluav taws xob nyob qhov twg nyob qhov twg?
Lub plab feem ntau yog nyob rau sab laug sab saud sab hauv qab lub diaphragm thiab txuas nrog zoo dua rau txoj hlab pas thiab nyob deb rau duodenum
Qhov sib txawv ntawm tus pab T cells thiab cytotoxic T cells yog dab tsi?
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
Lub luag haujlwm ntawm T cells thiab B cells yog dab tsi?
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
