Terminal bronchioles khij qhov kawg ntawm kev faib ua cov pa ntws ua pa system thaum ua pa bronchioles yog qhov pib ntawm ua pa faib qhov chaw sib pauv roj. Txoj kab uas hla ntawm bronchioles ua lub luag haujlwm tseem ceeb hauv huab cua ntws.
Ib yam li ntawd, koj tuaj yeem nug, lub ntsws ua pa yog dab tsi?
Cov pa ua pa yog qhov kawg faib ntawm cov bronchioles hauv lub ntsws. Lawv yog kev txuas ntxiv ntawm lub davhlau ya nyob twg bronchioles thiab muaj kwv yees li 0.5mm hauv qhov loj 1. Lawv tau suav nrog cov cuboidal epithelium yooj yim thiab muaj cov txheej nyias nyias ntawm cov leeg nqaij thiab cov nqaij ywj 2.
Ib yam nkaus, puas muaj cov leeg nqaij nyob hauv cov pa ua pa? Nyob ntawd tsis muaj pob txha mos, lossis qog, qee yam cov nqaij du tseem muaj, muaj yog tsis muaj cov cell. Lub epithelium yog columnar lossis cuboidal. Cov ceg kawg ntawm cov bronchioles hu ua lub ntsws bronchioles . Cov no muaj a txheej cov nqaij du ib puag ncig lawv lub lumens.
Ua raws li qhov no hauv kev txiav txim siab, hom epithelium pom nyob rau hauv lub davhlau ya nyob twg bronchioles?
Cov lub ntsws bronchioles pib muaj ciliated columnar epithelium cov ntaub so ntswg uas sai sai hloov mus rau ib tug tsawg cuboidal epithelium cov ntaub so ntswg . Mucous thiab seromucous qog thiab diffuse lymphatic cov nqaij yog txuam nrog me dua bronchi tab sis tsis yog pom nyob deb rau thaj tsam uas muaj cov phaj pob txha poob.
Puas yog bronchioles muaj cov ntaub so ntswg sib txuas?
bronchiole - muaj tsis muaj pob txha mos, tus nqi ncaj ncees ntawm cov leeg du, thiab tsis tshua muaj ib puag ncig cov ntaub so ntswg sib txuas . Lub epithelium maj mam ua qis dua thiab poob ob qho tib si cell thiab cilia.

Dab tsi yog qhov sib txawv thiab qhov zoo sib xws ntawm cov khoom sib tsoo thiab qhov kov zoo?
Dab tsi yog qhov sib txawv thiab qhov zoo sib xws ntawm 'crude' kov thiab 'nplua' kov qhov hnov? Nyuaj kov yog hais txog kev nkag siab los ntawm kev txhawb nqa ntawm cov neeg txais khoom ntawm qhov tsis nkag siab nrog cov teb loj. Hauv kev sib piv, kev kov zoo yog hais txog cov neeg txais khoom ntawm kev nkag siab siab nrog cov chaw txais me me
Dab tsi yog qhov sib txawv ntawm clonal nthuav dav thiab xaiv clonal?
Thaum cov tshuaj tiv thaiv kab mob tiv thaiv kab mob tiv thaiv kab mob, nws qhov epitopes thaum kawg yuav ua haujlwm nrog B-lymphocytes nrog B-cell receptors ntawm lawv qhov chaw uas ntau dua lossis tsawg dua haum thiab qhov no ua rau cov B-lymphocytes. Cov txheej txheem no yog hu ua kev xaiv tus kheej. Qhov no yog hu ua clonal expansion
Dab tsi yog qhov txawv ntawm ER ntxhib thiab du ER Dab tsi yog ER ua qhov sib txawv hauv txhua kis?
Ob qho tib si du thiab ntxhib endoplasmic reticulum pab hauv kev tsim thiab khaws cov proteins Qhov sib txawv tseem ceeb yog tias ib qho muaj ribosomes rau nws thiab lwm yam tsis. Rough ER zoo li cov nplooj ntawv. RER sib sau ua (ua) thiab ntim cov protein. RER tau txuas nrog lub nuclear membrane
Dab tsi yog qhov txawv ntawm cheeb tsam sib txawv thiab thaj tsam tas li ntawm ib qho tshuaj tiv thaiv?
Cov cheeb tsam sib txawv no, muaj li ntawm 110-130 amino acids, muab cov tshuaj tiv thaiv kab mob nws qhov tshwj xeeb rau kev khi antigen. Cov cheeb tsam sib txawv suav nrog qhov kawg ntawm lub teeb thiab cov saw hnyav. Lub cheeb tsam tas li txiav txim siab cov txheej txheem siv los rhuav tshem antigen
Dab tsi yog qhov txawv ntawm qhov tseeb qhov pib thiab qhov sib txawv qhov pib?
Qhov pib tsis txaus yog qhov tsawg kawg ntawm kev txhawb siab xav tau rau ib tus neeg kom pom qhov kev txhawb siab 50 feem pua ntawm lub sijhawm. Qhov sib txawv ntawm qhov sib txawv yog qhov sib txawv me tshaj hauv kev txhawb nqa uas tuaj yeem kuaj pom 50 feem pua ntawm lub sijhawm
