Kiko epithelial: i kaitiaki rohe

A, no te kōrero iwi e pā ana ki tenei ahua o te papanga, mahara rawa ahau i te kiri, ahakoa te kikokiko epithelial - he reira, i roto i te parau tumu, te ahua o "kaitiaki rohe". wehea ia i tetahi ki tetahi whekau, kua roto i te reira i roto i te hanganga o te mucous. Heterogeneous epithelial kikokiko, hanganga me te mahi o nei, e toaati i roto i te ara motuhake mo ia momo o te papanga. Mō te aha momo o korero? Pānuitia atu.

He āhuatanga noa āhuatanga o ngā momo katoa - pūtau e te hunga i roto i te whakapā tata ki tahi e te tahi, pinepine i roto i ngā papa, e tika ana ki te mahi arai o te kiko epithelial. Ano, katoa momo o kiko epithelial i roto i te noa, ko e o te hanganga pātata, kua wehea tonu ratou i te kiko tūhonohono - huaina tenei hanganga ko te membrane basement.

I roto i te epithelium whānui he kuware (he paparanga kotahi) me te kiri (e rave rahi). Fakatatau ki ai, pea rawa rerekē te hanganga o te kiko epithelial.

Ka taea te paku papatahi epithelium Simple i roto i te āhua. huaina ana tēnei momo ko te squamous. Ia rārangi nga pūkahukahu, oko toto, kōwhao ngakau. Ano, Ko enei pūtau i roto i te papa o runga o te kiri, me te mucosa-waha.

Ehara i te mea uaua ki te imi i te āhua o ngā pūtau epithelial pūtoru. E kitea ana ēnei pūtau i roto i te repe, aerodynamics, repe me nga tubules tākihi. I tua atu, kėia ratou te epithelium Germinal i roto i te ovaries o te wahine a me komurumurua o nga tangata.

He kuware me paparanga epithelium Prismatic. Ko te pūtau i te āhua o tutaki elongated. Karihi i roto i enei pūtau e "huna" whawhe membrane ofi ange ki a atu i te mata. Well, i roto i te kopu, raina ratou nei mata, he reira tino pai - pukuriri rawa reira Wenerei. Ētahi o ēnei pūtau he wahi o nga whekau tairongo - kakara, reka me te rongo.

kua he growths rawa āhua e nohopuku tāwakawaka taea ki te whakatairanga i te tahi mea e te mea tata ki a ratou ciliated epithelium hanga tīwae. Ratou "ora" i roto i te ihu, me te ... i roto i te ngongo kākano i roto i nga wahine, tuku ki a ratou whakatairanga i te hua manu ki te kōpū.

huaina prismatic epithelium glandular kei ngā pūtau secreting. I te tahi taime secreting pūtau neke atu i hanga tīwae. Kei hea nga pūtau e taea te waihanga i tētahi ngaro? Ko reira te pūtau o epithelial kikokiko, mua te ara no te ite taa'e. Na te "tohunga" taea e ratou rawa rerekē. Whai wāhi i roto i te hanga o whākōkī, hormones, waiu, hūpē, werawera, te waki i me te huware. O te akoranga, e taea ana ki te whakaputa i te pūtau-tahi repe, repe o te take, arā, o maha pūtau epithelial katoa o enei matū. huaina te pūtau kotahi pūtau oko. I te tīmatanga i huaina ratou enterocytes, no te mea te nuinga o enei pūtau i roto i te whēkau iti. Otiia ka tahuri te reira i roto i katoa e kitea e ratou i roto i te kirikamo o te kanohi, me te i roto i te pūnaha romahā, a i roto i te aerodynamics o te repe.

Hea te tukanga nui o te waku me te mōrea o te whara, te tinana hanga epithelium matatini - te tetahi ano e ngā o te maha paparanga tonu. Kei te korero tatou e pā ana ki te kiri, me te mucosa-waha. I runga i te pūtau mata kiri tikanga i roto i nei te pūmua maha-keratin i roto i te mangai keratin pūtau he iti, koia ko tino rerekē te kiri pa, me te membrane mucous o te mangai.

Ko te tino rerekē mahi kiko epithelial. e kore te mea tino tonu te rārangi i raro nei.

Ko te mahi tiaki. Epithelium ārai kino aunoa, weranga matū, araunga he arai ki te mate, me te tiaki i te pūtau i te mate wai waiwai.

sensations Taumahi: pūtau motuhake o epithelial puka kiko whekau sensations.

mahi Secretory: kua whakaahuatia i roto i te taipitopito i roto i te wāhanga o te epithelium glandular.

Absorptive: i roto i te kōpiro iti i roto i te epithelium o te absorption o ngā matūkai kawea i roto i te.

Excretion: repe werawera te huna hoki matū e hiahiatia i roto i te epithelium tākihi hoki ahei o whai wāhi i roto i te filtration, a hoki i roto i te reabsorption.

Tūringiringi: i roto i te epithelium kikokore i roto i te wahi romahā ki te tinana, me te i te haurehu tomo.

Purenga mahi: epithelium airway cleans te rangi i te puehu.

waku iti: epithelium iaia te whakaiti te waku i waenganui i te taiepa oko, me te pūtau toto.

Ka rite ki taea kite koe, he rota o ngā mahi, no te mea momo maha. Ka lau koe ētahi atu mōhiohio e pā ana ki tenei i roto i te pukapuka pai o te histology.
