Zaminyewa minofu: pa asilikali olondera malire

Pamene anthu kulankhula za mtundu uwu nsalu Ndimakumbukira makamaka khungu, ngakhale zaminyewa minofu - izo ziri, mfundo ngati "wolondera malire". Iye wosiyana ziwalo wina ndi mnzake, iwo ali zikuchokera mucous lapansi. Sakanikira zaminyewa minofu, kapangidwe ndi ntchito ya amene cholukanalukana mwapadera pa mtundu wa nsalu. Zimene mitundu ya kulankhula? Werengani zambiri.

Makhalidwe wamba mbali ya mitundu - maselo ali pafupi zedi ndi mzake, kawirikawiri zigawo, chifukwa chotchinga ntchito ya minofu zaminyewa. Komanso, zonse mitundu ya minofu zaminyewa ofanana ndi a nyumba ya pafupi, iwo nthawizonse olekanitsidwa ndi minofu connective - mapangidwe uwu umatchedwa chapansi Kakhungu.

Mu epithelium ambiri ndi losavuta (a wosanjikiza limodzi) ndi laminate (angapo). Choncho, kapangidwe ka minofu zaminyewa mosiyana kwambiri.

Zambiri epithelium akhoza pang'ono flattened mu mawonekedwe. mtundu amenewa amatchedwa squamous. Iye mizere mapapo, mitsempha ya magazi, cavities mtima. Komanso, maselo amenewa ali mu zigawo kumtunda kwa khungu ndi m'kamwa mucosa.

N'kosavuta kuti atchule mawonekedwe a kiyubiki maselo zaminyewa. Maselo amenewa akupezeka zopangitsa kuti, ducts, zopangitsa ndi tubules aimpso. Komanso, zimapanga epithelium germinal mu thumba losunga mazira a akazi ndi machende anthu.

Prismatic epithelium yosavuta magawo. maselo ndi mawonekedwe a mipiringidzo elongated. Mtima maselo amenewa ndi "zobisika" chapansi Kakhungu pafupi ndi kutali pamwamba. Chabwino, mmimba, amene nkhope iwo munzere, ndi kothandiza kwambiri - kwambiri mwamakani kumeneko Lachitatu. Ena mwa maselo amenewa ndi mbali ziwalo imalandira - kununkhiza, kulawa kumva.

Ciliated columnar epithelium ali zophuka mwapadera zooneka kwenikweni undulating athe kulimbikitsa chinthu pafupi iwo. Iwo "moyo" mu mphuno ndi ... mu Ukalawu mu akazi, kuzipatsa kulimbikitsa dzira kuti chiberekero.

Glandular epithelium otchedwa prismatic chikukhudza secreting maselo. Nthawi zina secreting maselo kuposa columnar. Kodi maselo angalenge chinsinsi? Ndi maselo a zaminyewa minofu kale njira ya specialization. Ndi "akatswiri" angathe kukhala osiyana kwambiri. Chinkhoswe kupanga michere, mahomoni, mkaka, ntchofu, thukuta, phula ndi malovu. Inde, zinthu izi analephera kupanga limodzi tating'ono zopangitsa, zopangitsa mlanduwo, wopangidwa mwa maselo ambiri zaminyewa. Gawo limodzi otchedwa maselo muyeso. Poyamba iwo anali kutchedwa enterocytes, chifukwa ambiri a maselo amenewa ndi intestine yaing'ono. Koma ndiye kunapezeka kuti iwo alipo mu conjunctiva diso mu dongosolo kupuma, ndi ducts wa zopangitsa lapansi.

Kodi njira yaikulu ya mikangano ndi chiopsezo kuvulazidwa thupi anzathu zovuta epithelium - yemweyo amene nthawi zonse imakhala zigawo zingapo. Tikuyankhula zokhudza khungu ndi m'kamwa mucosa. Pa maselo a khungu pamwamba oyenerera amene Mipikisano keratin mapuloteni mu pakamwa keratin maselo ang'onoang'ono, kotero khungu kukhudza ndi mucous nembanemba mkamwa n'chosiyana kwambiri.

Zaminyewa minofu ntchito ndi osiyana kwambiri. Mndandanda m'munsimu si kwathunthu zonse.

Ntchito zozitetezera. Epithelium chindiletsa kuwononga makina, amayaka mankhwala, naonekera chotchinga ndi AIDS ndi kuteteza maselo kuchokera zakuya imfa madzi.

Ntchito zomverera: apadera maselo a zaminyewa minofu mawonekedwe ziwalo zomverera.

Secretory ntchito: limafotokoza mwatsatanetsatane mu gawo la epithelium glandular.

Absorptive: mu wa intestine yaing'ono mwa epithelium wa mayamwidwe wa zakudya ikuchitika.

Excretion, zopangitsa thukuta secrete zinthu osafunika mu epithelium impso komanso amatha kukhala nawo mu kusefera, komanso mu reabsorption.

Mayamwidwe: kupyolera epithelium wochepa thupi thirakiti kupuma mu thupi kuchokera ku mipweya ndi kusinthitsa.

Kuyeretsa ntchito: airway epithelium aisadza mpweya kuchokera ku fumbi.

Yafupika mikangano: mtima epithelium ayeziyo pakati pa khoma chotengera maselo magazi.

Monga mukuonera, kwambiri ntchito, chifukwa mitundu. Zambiri za izi mudzawerenga mu mabuku wabwino wa histology.
