Pūtau oko: hanganga āhuatanga, kōwhiringa ingoa me te wāhi o te localization

Ko te tinana tangata - ko te milioni o ngā pūtau o ngā āhua, momo me te rahi. E na iti e whakaaro ratou, ka titiro ratou anake i raro i te karu ratou. I roto i te meka, te pūtau - ko te poraka hanga mōkitokito o ararewa kikokiko, okana, ngā pūnaha, me te rauropi katoa. Ahakoa te rerekētanga i roto i ngā puka mō ngā pūtau katoa ko te hoahoa whānui o te hanganga. ngā ratou o te membrane waho, semiliquid te karihi pokapū, me te cytoplasm. Mō te momo rerekē o ngā pūtau e taea e te korero roa, engari ka kia whakaaro tenei tuhinga kotahi anake te momo, ka karanga pūtau oko. Ka tamata tatou ki te matau ki ta ratou e, te wahi e kei a pehea ki te mahi.

kōwhiringa taitara

E mohiotia taua pūtau i raro i te maha o ngā ingoa. Kei te maha te parau "kapu enterocyte", "oko ekzokrinotsid" me "inuwai grandulotsit" whakamahia. pūtau oko Latin huaina caliciformis enterocytus. I te tahi taime te wā "oko pūtau," e pā ana hoki pūtau oko. He ōrite ki tahi i te tahi, me te whakamahia rite taurite katoa o enei ngā.

kitea te ingoa te āhua rerekē o te pūtau. titiro ratou rite paku muranga he roroa, karaihe kuiti whakarunga.

Pūtau o tenei momo no ki te epithelium o nga kiriuhi mucous me e whai wāhi i roto i te hanga o te hūpē. e kitea i roto i te tinana e rua tangata me te kararehe ratou.

Localization. whekau

ngā pūtau oko he wahi o te maha whekau epithelial. Ko tētahi o nga wahi o localization - te paru. epithelium intestinal he hanganga, kaua matatini. fakatahai reira e rave rahi ngā momo o enterocytes, tae atu i te limbic, oko, acidophilus, beskaemchatye, endocrine, me ētahi atu painga rerekëtanga. He repe pūtau-tahi ki ngā mahi rerekē katoa o ratou. Hei tauira, whai wāhi te pūtau epithelial limbic i roto i te kōpako nakunaku me te absorption. Oko haepapa mo te hanga o te hūpē (kite i raro korero atu). pūtau endocrine hua hormones tuleki, pūtau acidophilus Punnett hua whākōkī atu kūnatu. Taumahi pūtau undifferentiated - houtanga o te epithelium.

E whakanohoia pūtau kapu o te whēkau i runga i te Villi intestinal. E hanga ana ratou i runga i te taua i waenganui i nga pūtau limbic. I runga i te wahi apical o te Villi me i rawa tubular o te membrane mucous, ka karanga repe liberkyunovymi ranei crypts intestinal, e kore e kitea ngā pūtau oko. Ahakoa i reira he okotahi onge.

I roto i te kōpiro iti o tenei momo o ngā pūtau nui. 9.5% enterocytes - oko pūtau epithelial. Ano, faarahi ratou tokomaha ki te kopirua distal. E tohaina mangai ratou i runga i te tihi o te turanga o te crypts me Villi, ratou nui iti i runga i te Villi ratou.

Airways

oko tetahi atu localization wahi pūtau exocrine - te wahi romahā. Here i roto i enei pūtau he tata 30% o te epithelium. Kei te hoki whakaritea nga pūtau putawa. Kei roto ratou vacuoles ki tonu i te secretion mucous. Vacuoles i whakawhänui i te wahi apical. Kei te wahi kaki o te pūtau te matatini Golgi me maha pungaraungao. Kei te whakaratohia airway microvilli pūtau oko, e, i muri i riro kite hūpē.

he huritaiāwhio i roto i te natura, e whakawhirinaki i runga i ngā āhuatanga o waho, arā, te pāmahana, me te haumākū hūpē.

pūtau oko Conjunctival

Ko te wahi i muri o te localization o ngā pūtau kapu - te kanohi kirikamo. He maha nga mucosa conjunctival. Ko rerekē i te hūpē huna ana i roto i te epithelium o te tahi atu whēkau te ngaro, huna ana e enei pūtau. pūtau oko Conjunctival kei i te paparanga basal me he porotītaha, me te porohita. Hūpē, e synthesize ratou, ka huna, herea i roto i te ahua o te whatunga e hopu me tuhi nga tinana ke me te huakita. I roto i rarapa, pakaru te whatunga kei te ka neke ki te mata medial, te tango i nga kanohi i te otaota, me te huakita.

pūtau oko i roto i te repe taiaki

e kitea i roto i nga aerodynamics putanga o te repe taiaki ngā pūtau kapu. e kore e ratou kei runga i te roa katoa o te tau mahani, a i roto i to ratou wahi whānui. He exocrine repe i hanga mucosa.

repe hūare

he taonga i roto i ngā pūtau oko ano te repe salivary. E tū ana tata te mangai, ka huna hūpē, te kaha ki te whakaora i te arai matū ki papapūata. Ki te tau, heke te maha o ngā pūtau kapu i roto i te repe salivary te. ngoikore arai antimicrobial.

Ētahi atu kōrero mō te āhuatanga

pūtau oko hua hūpē rewakore i huaina e te mucin. Mucin ngohi te mucosa, ētahi wā kohikohi ki te matotoru 1.5 mm o. Ki te hanga i te reira, mimiti granules mutsitogennye wai, me te pupuhi. He maha ngā mahi hūpē o ngā pūtau oko. I roto i te kopu, moisturizes taiaki me te whēkau mucosa reira tinana whakatairanga pekitīlia me tirotiro intestinal, he wahi o te nakunaku taiepa. Ko te kirikamo anake Humidification kua he mahi tiaki i roto i nga repe salivary - arai.

Paturopi oko pūtau

Tikanga paturopi ki oko he mea motu ke i roto i te toto ngā pūtau. Ki te tāutuhia te tātaritanga o te toto i te rua enei paturopi, te auraa e te manawanui he colitis ulcerative. Na reira, hoki paturopi whakaritea oko tātaritanga pūtau mo te tātaritanga pārōnaki o ma'i mate whēkau inflammatory.
