Epithelial'aʻaʻa: i palena kiaʻi

I ka olelo e pili ana i keia ano o ka lole kanaka, au e hoomanao hoi i ka ili, eia nae ka epithelial'aʻaʻa - ia mea, ma ka rula, he ano o ka "palena kiaʻi". Ua kaawale mai kekahi i kekahi, nā loko, ka mea, ua loaʻa ma loko o ka haku mele 'ana o ka mucous. Heterogeneous epithelial'aʻaʻa, 'ole a me ka hana o ka i i interconnected ma ka kūikawā ala no kela a me keia ano o ka lole. About mea ano o ka olelo? E heluhelu hou.

A ano like hiʻona o nā ano - aeee i mea i loko o ke kaua'ō'ō ihe i kekahi i kekahi, pinepine ma ka papa, no a hiki i ka papa ke'ākeʻakeʻa mai o epithelial'aʻaʻa. No hoi, a pau ano o epithelial'aʻaʻa i na mea i ana o ka moku e nā hale, ka mea e mau kaawale e connective'aʻaʻa - Ua kapaia keia ho okumu i ka hale ilaloʻili lahilahi.

I mau epithelium mea puni (he hookahi, ahu iho) a me ka lamineka (mau). Alaila, o ka 'ole o ka epithelial'aʻaʻa i e loaʻokoʻa.

Simple epithelium hiki ke iki flattened ma shape. Kēiaʻano ua kapaia he squamous. He laina ka maʻiʻaʻai, ipu koko, naau cavities. Nō hoʻi, i kēia mau keena i loko o ka luna papa o ka ili a me ka moʻolelo mucosa.

Ia mea,ʻaʻole paʻakikī e koho i ke kinona o ka cubic epithelial keena. Mau keena i loaʻa i loko o ka glands, ducts, glands, a me kaʻaʻa puʻuwai tubules. Eia hou, e lakou i ka germinal epithelium i loko o nā ovaries o na wahine, a me na kanaka o ka hoʻi.

Prismatic epithelium ka poe noonoo ole a me ka pona. Ke keena i ke kinona o ka elongated mau kaola. Nuclei i loko o kēia mau keena e "hunaia" hale ilaloʻili lahilahi pili i ka a aku, mai ka 'ilikai. Ua pono, i loko o ka'ōpū, nona ka maka ka mea, laina, ia mea loa efficient -ʻoi aku ko lākouʻano pākīkē 'ia ma laila. Kekahi o kēia mau keena i kekahi hapa o ka sensory nā loko - nā dudima,ʻaiʻana a me ka lohe.

Ciliated columnar epithelium i ka pela hoʻokino ka ulu o ke mea e hoʻokēʻai ai undulating hiki ke hoʻohanohano i kekahi mea i mea kokoke ia ia. Ka mea, "ola" i loko o ka ihu, a ... ma ka fallopian paipu i loko o nā wāhine, hiki ia lakou, e paipai i ka hua manu i ka uterus.

Glandular epithelium kapaia prismatic ec pee keena. I kekahi manawa, pee keena hou ma mua o columnar. Auhea na keena e ke hana i kekahi mea huna? He na keena o epithelial 'aʻaʻa, hala ke alanui o ka specialization. A me ka mea hiki e loa okoa ka "poe akamai i". Hana i loko o ka? Iecaianoaaiiie o nā'ūhū, hormones, ka waiu, mucus, hou, mahuahua a me kou tuha. O ke ala, a pau o kēia mau waiwai e hiki i ka paka i ka hookahi-aa? Glands, glands o ka hihia, iloko olaila ka nui epithelial keena. A hookahi aeea kapaia poepoe lā ia keena. Initially ua kapaia ka mea, enterocytes, no ka mea, ka hapanui o kēia mau keena ma ka liʻiliʻi liʻiliʻi. Akā, laila, e huli mai i ka mea, a pau loa imua i loko o ka conjunctiva o ka maka, a me ka ÷ naehana hanu'ōnaehana, a ma na ducts o na glands.

Where na keʻano o ka hanaʻana nui o ke kū'ē, a me ka pilikia o ka hewa, i ke kino kūkulu luna 'epithelium - ka ia kekahi e mau ana oia no kekahi mau papa. Mākou e kamaʻilio e pili ana i kaʻili a me ka moʻolelo mucosa. Ma ka ili 'ilikai manaʻo keena ma a nunui-keratin kumuʻiʻo i loko o ka waha keratin aeee mea liʻiliʻi, no laila mea me ka nui loa okoa ka hoʻopā ili a me mucousʻili lahilahi o ka waha.

Epithelial'aʻaʻa kuleana pili i ka loa okoa. I ka papa ma lalo mea,ʻaʻole loa piha.

Ke aiiay kuleana pili i. Epithelium ua ālai 'mechanical e poino, Nine Inch'ā, posing i ke'ākeʻakeʻa mai i ka maʻiʻaʻai, a i malama i ke keena, mai ka hp'pnphp wai poho.

Launch ka waiʻona ma ke: hana kūikawā keena o epithelial'aʻaʻa palapala nā loko ka waiʻona ma ke.

Secretory hana: ua i ho'ākāka 'ia i loko o au mamuli o ka pauku o ka glandular epithelium.

Absorptive: ma ka poe uuku liʻiliʻi ma ka epithelium o ke omo o ka māhuaola ua lawe mai.

Excretion: hou glands pee hua'ōlelo i makemake 'ona i loko o ka hakuʻala epithelium i hiki ke komo i loko o ke kānana, a me kekahi ma ka reabsorption.

Maholahune: ma ka lahilahi epithelium i loko o ka naehana'āpana i loko o ke kino, a mai ka permeate kinoea.

Huikalaia i hana: airway epithelium lākou ma ka hoʻomaʻemaʻe i ka lewa mai ka lepo.

Hoemiia kū'ē: vascular epithelium ho'ēmi i kā kū'ē ma waena o ka moku paia a me na keena koko.

E like me 'oe ke ike, he hailona o ka oihana, no ka mea, he nui loa? Ueo. Hou aku 'ike e pili ana i kēia' oe, e heluhelu i loko o ka buke maikai o ke histology.
