Kia mea a, i mua i te hoatu e koe te mahi i muri: whakaahua ate mahi i roto i te nakunaku. Ki te mahi i tenei, me ako tuatahi koe tona hanganga matüora, āhuatanga me huarahi o te ate e hiahiatia ana mō te nakunaku tika o ngā matū waro e hanga ake te kai. Ka ēnei take e whakatutuki i roto i tenei tuhinga.

mahi secretory

Ko te ate Ko te repe nui rawa i roto i te wahi gastrointestinal, tūturu i roto i nga kararehe whai tuaiwi, me te tangata. Kei a ia ko ngā pūtau parenchymal, ka karanga hepatocytes. He te pūtau ate kotahi kotahi, neke atu rānei karihi me ngā o rua nga wahi i huaina iaia me te biliary. rōpū whakamutunga hepatocyte whakapā ki sinusoids e riro te toto i te uaua ate. Tenei wahi synthesizes kūhuka, pūmua, huaora me lipocomplexes.

whakahaua te tahi atu taha o te hepatocyte ki ate capillary. Kei te karangatia e te reira i biliary. hua te reira i bile. rere te reira i atu ki te capillary, a i reira - i roto i te aerodynamics. Ko te kupu, i roto i te ate ate hauora hanga taha hepatocyte e kore e tomo te bloodstream, mai wehea te capillary biliary i te tinana o ngā pūtau sinusoidal ate.

Me kï reira e e whakarōpū i te hepatocytes ki te hanga i wāhanga, o nei e nga aerodynamics ate i roto i, me te ki waho. hanumi ratou a rua puka ahunga matua - mahue me tika. mai ratou i roto i o te taupa pokapū o te ate. Na ka hanumi ki te hanga i te tau mahani noa e toro i tona kuwaha, me te vpadot i roto i te gallbladder. Ko te kupu, ko te ate, ko te ate okana secreting. Ka Anatomy o ate, hanganga me te mahi au tōngāmimi kia whakaaro e tatou atu.

E titau te tuku o te ate?

Pūhui e tauturu piri macromolecule wāhanga organic matatini o kai, pā ana ate. E ohipa te reira i runga i te lipids kitenga, tahuri ratou i te āhua rewakore ki te hanga i te whakaehunga. matū mata-hohe e - puritia e te cholic waikawa ate - chenodeoxycholic me cholic. whakaehu ratou riro ngako kai i te puku ki te duodenum, ngä mahia ratou wāwāhi e whākōkī o te repe taiaki - lipase.

Ko te hanganga matüora o ate

E matau te hanganga o nga āhuatanga hanganga o nga matamata ate, wahi o hepatocytes biliary, me te te hanganga matüora, kua tika whakaahua koe te mahi o te ate i roto i te nakunaku. Kua kitea Gastroenterologists e i roto i te ate rere te tukanga matatini o te kirihou me te pākia pūngao. Ate iho ko te parauri oriwa wai marama ranei. Kei reira 98% te wai, me te uhi, cholesterol, waikawa cholic, lecithin, huaora me whākōkī.

Whakaaroa te hanganga me te tohanga o ngā waikawa ate. E hanga e ratou i te waipiro pūtaiaki - cholesterol. Ko hoki ia wahi o kiriuhi pūtau. I roto i te hepatocytes oxidized cholesterol te ka hanga i te waikawa ate tuatahi. Ka taea e ratou mutate, hoko tuarua: metaholevuyu me deoxycholic. Ko te hunga, i roto i te tahuri, i whai ahua ai complexes ki waetahi pūmua - taurine me glycine.

Ko te tino urupare ēnei complexes me e roto i roto i te wai i roto i te puka o te konutai pāhare pāporo ranei Mariao. uhi ate - tetahi atu wāhanga matüora, te matua o te mea bilirubin. Kei te hanga e te reira e te whakangaromanga o te pūtoto i puta i roto i te macrophages ate - pūtau Kupffer rite te pai rite i roto i te kōateate. Lecithin - he wāhanga o te ate. Kei te hanga e hoki te reira i roto i te ate, me whai wāhi nui i roto i te pākia o waikawa ngakongako me cholesterol e tukupu ana tona taumata. Ia e hoki wahi i roto i te emulsification o ngako.

Aha nga āhuatanga o te ate?

Ka ako te hanganga matū o te secretions o te ate, e taea tika tohu tona tūranga i roto i te rärangi o te mea waro me ki whakaaro nga mahi taketake o te ate i roto i te nakunaku, he rere ke nei. Hei tauira, kei roto te reira i te hopiwē me te waikawa takoha ngako rāpoi nui wāwāhi ki te hunga iti. pānga ate nga whākōkī hydrolyze nga warowaihā me te pūmua: amylase me trypsin, te whakanui ake ratou āhuatanga catalytic. I roto i te whākōkī pekitīlia - pepsin - mahi reira te ara te ritenga, i.e. inhibits tona mahi, e arata'i ki te hua koi i roto i te pH o tirotiro pekitīlia, mai heke te kawatanga.

Wehe o ate whakatairanga rongoā absorption o Mariao kohuke, o huaora A me D, me te waikawa amino. Ko te mea ngaro o te ate regulates te pūkaha me te secretory mahi o te whēkau iti. Ko te tūranga o te ate i roto i te nakunaku tenei.

Pūhanga o te ate, me te zholcheotdeleniya

I mua, kua ako matou nga āhuatanga o te secretion ate whakaputaina e wahi biliary o hepatocytes. Na i kitea ano e matou e te hanganga, ngā āhuatanga o te ate, me tona faufaa i roto i te nakunaku te honohono. E kawea ēnei tikanga i roto i rua io te tangata, me te ara humoral. whakarei ate hanganga te rite te whakautu pūpū ki te whakaongaonga interoceptors taiepa kiriuhi mucous o te kōhao-waha, puku, whēkau iti.

Gallbladder: tona hanganga, me te tūranga i roto i te nakunaku

Ka rite ki te okana uaua, kua tū ai i raro i te mata o raro o te ate. He he kaki, tinana, me te raro. Kia koutou tikanga anatomically obosnuete o tona mahi, ka taea ngāwari koe whakaahua i te mahi o te ate i roto i te nakunaku. Kei te tonu hanga ana ia i roto i te ate, me tukua ki te duodenum tika i roto i te wa o te whakauru ki roto ki te tinana kai. I waenganui i kai ngaro takoto i roto i te gallbladder.

tikanga tātaritanga o tūhuratanga o ate

Hoki tauhohe pūkoro noa i roto i te wahi gastrointestinal titau etahi whaiaroaro, me te matüora secretion ate. E physiologically whakatikaia e koe te tuhituhi i te mahi o te ate i roto i te nakunaku ki te he noa ona tawhā haumanu. E whakaritea ratou e te tokomaha hautanga intubation duodenal.

I roto i te wāhanga tuatahi o te ako i rite te hautanga basal. kia whai te reira i te tae kōwhai marama, me te pH nui ake i 7. I roto i te rua i te wāhanga ki te sphincter kati o oddi ngaro tu i roto i te uiuia e kore kia. I te toru o nga wā o te ako, he taumata hauora noa o te ate e whai ake: rōrahi - i 3 ki te 5 ml, Tae - te marama parauri. pumau te tuawha wāhanga e pā ana ki te haora. rerekē tae secretion ate i oriwa (ate vesical) tae noa ki te kōwhai-amipere. Ko tōna pH = 6.5-7.5 me te mātotoru o e pā ana ki - 1038. Ko te wāhanga whakamutunga, te tohanga o ate ate, pumau ake ki te 20 meneti. heke te kiato ki 1011, pH = 7,5-8,2.

Ine i te tawhā i runga, ka kia tohu o disorders pathological o te ate, au tōngāmimi aerodynamics ranei. Ko te momo tino noa o te mate ko te hanganga o kohatu i roto i te tōngāmimi tika ki nui haere pokey o te inu, me te he takahi o tona mahi contractile. Ka rite ki a koutou e taea te kite, i roto i tenei tuhinga i arotakehia matou, ka ako te ngaro o te ate - ate, tikanga, me ona mahi i roto i te tukanga o te nakunaku.
