Indima Bile e ukugaya. Chaza umsebenzi we Bile e ukugaya

Ake sithi, ngaphambi ukubeka umsebenzi olandelayo: ukuchaza Bile umsebenzi e ukugaya. Ukuze wenze lokhu, kuzomele uqale ukufunda kwamakhemikhali ngezithako zawo, izakhiwo kanye nezindlela of Bile ezidingekayo ukuze kokudla esiswini efanele izinto eziningi eziphilayo ezakha ukudla. Lezi zinkinga ziyoxazululwa kulesi sihloko.

umsebenzi secretory

Isibindi yisona indlala ngobukhulu kuleli pheshana emathunjini, esivela izilwane yezilwane ezinomgogodla futhi indoda. Siqukethe parenchymal cell, elibizwa ngokuthi hepatocytes. A esitokisini olulodwa hepatic has eyodwa noma ngaphezulu nuclei futhi liqukethe izingxenye ezimbili ngokuthi semithambo kanye biliary. party Kugcine hepatocyte contact nge sinusoids ukuthi igazi emithanjeni hepatic. Le ngxenye synthesizes glucose, amaphrotheni, amavithamini kanye lipocomplexes.

Enye uhlangothi hepatocyte baqondiswa ekufezeni Bile capillary. Ibizwa ngokuthi biliary. Uveza Bile. Ngulona logeleta waya capillary, futhi kuwo - ku mapayipi. Ngakho, ngo-isibindi Bile enempilo elakhiwe hepatocyte ohlangothini akusho lingene egazini, kusukela capillary biliary ahlukaniswa umzimba amaseli hepatic sinusoidal.

Kufanele kuqashelwe ukuthi hepatocytes ziqoqwa ukwakha izingxenye, okuyiqembu Amapayipi Bile ngaphandle nangaphakathi. Bona uhlangane futhi ifomu izinkomba ezimbili eziyinhloko - kwesokudla noma kwesokunxele. Eza aphume Lobe emaphakathi kwesibindi. Bese uhlangane ukwakha imbobo ezivamile ezisabalele kusukela esangweni layo futhi vpadot e le gallbladder. Ngakho, kwesibindi iyona Bile isitho secreting. Anatomy of Bile, lokuphatselene nesakhiwo nemsebenti nenyongo sesinye ezocatshangelwa yithi phambili.

Edinga ukukhululwa kwe Bile?

Compounds esisiza macromolecule izingxenye eziyinkimbinkimbi ninamathele organic ukudla, Bile uyalandisa. It uba phezu lipids sextant, kokuwaguqulela kusuka esimweni zingaxazululeki ukwakha i emulsion. Esezandleni ze-Bile acid cholic - chenodeoxycholic futhi cholic - kukhona izinto ebusweni-asebenzayo. Bona emulsify amafutha ukudla wathola kusukela esiswini phakathi duodenum, lula eqhekeza yabo ngokukhokha enzyme kwamanyikwe - lipase.

Ukwakheka kwamakhemikhali Bile

Ukwazi isakhiwo izici isakhi iyizingxenye hepatic, izingxenye hepatocytes biliary, kanye ukwakheka kwamakhemikhali, uke kahle ukuchaza umsebenzi Bile e ukugaya. Gastroenterologists kwatholakala ukuthi esibindini izinqubo eziyinkimbinkimbi plastic ageleze namandla umzimba. Bile ngokwayo uketshezi noma ukukhanya omnqumo ensundu. Iqukethe 98% amanzi, kanye zombala, cholesterol, acid cholic, lecithin, amavithamini kanye enzyme.

Cabanga isakhiwo nokusakazwa of Bile acid. Basuke kwakhiwa kusuka utshwala steroid - cholesterol. Futhi ingxenye cell ulwelwesi. Ngo hepatocytes cholesterol is oxidized bese yakha eyinhloko Bile acid. Abakwazi liguquke, ekubeni yesibili: metaholevuyu futhi deoxycholic. Labo, esikhundleni salokho, yakha izakhiwo amaprotheni monomers - taurine kanye glycine.

Lezi izakhiwo kukhona esisheshayo kakhulu futhi eziqukethwe ketshezi ngesimo sodium noma ye-potassium nosawoti. Bile zombala - enye ingxenye kwamakhemikhali, main okuyinto bilirubin. Lakhiwa ukubhujiswa-hemoglobin okwenzeka macrophage isibindi - Kupffer amaseli kanye ubende. Lecithin - ingxenye Bile. Liphinde kwakheka isibindi udlala indima ebalulekile umzimba fatty acid cholesterol ukwehlisa izinga layo. Wabuye uthatha iqhaza emulsification kwamafutha.

Yini property Bile?

Njengoba usuyitadishile Ukwakheka amakhemikhali uketshezi kwesibindi, ungakwazi ikuveza yendima yayo ekuqhubeleni ukubhidlika udaba eziphilayo futhi ucabangele imisebenzi eyisisekelo Bile e ukugaya, okuyinto zahlukahlukene. Ngokwesibonelo, liqukethe yokuwasha kanye acid iqhaza amafutha molecule eqhekeza ezinkulu zenziwe kancane kancane. Bile kuthinta enzyme hydrolyze carbohydrate namaprotheni: Amylase futhi trypsin, okwandisa izakhiwo zabo okhanda amanye amathuba. Ngo-enzyme esiswini - pepsin - ke izenzo ngendlela ehluke ngokuphelele, isb kuvimbela umsebenzi wayo, okuholela waba ukwanda okukhulu kwezincwadi pH okuqukethwe esiswini, kusukela asidi incipha.

Kwemihlambi Bile ithuthukisa ukumuncwa izixazululo nosawoti amaminerali, amavithamini A no D, kanye nama-amino acid. Imfihlo isibindi ulawula motor kanye secretory umsebenzi emathunjini amancane. Lena indima Bile e ukugaya.

Izindlela zika Bile futhi zholcheotdeleniya

Ngaphambili, siye safunda izakhiwo uketshezi isibindi ezivezwa izingxenye biliary ka hepatocytes. Futhi siphinde sathola ukuthi ukwakheka, izakhiwo Bile kanye nekubaluleka kwalo ku ukugaya kuhlobene. Lezi izindlela abazenzi kokubili isimiso sezinzwa somzimba womuntu nendlela humoral. Bile kumiswa sithuthukiswa impendulo reflex stimulation interoceptors izindonga nolwelwesi lwamafinyila we ngomlomo ingaphakathi, isisu, amathumbu amancane.

Gallbladder: isimo sawo futhi indima ukugaya

Njengoba isitho kwemisipha, itholakala ngezansi onqenqemeni engezansi kwesibindi. It has a intamo, umzimba kanye phansi. Uma indlela anatomically obosnuete imisebenzi yayo, khona-ke ungakwazi kalula ukuchaza umsebenzi Bile e ukugaya. Yena njalo ukwakha esibindini futhi adedelwa duodenum nje isikhathi yokwemukela emzimbeni ukudla. Phakathi ukudla imfihlo zibekwe gallbladder.

izindlela zokuxilonga of ukuphenywa kokuphulwa Bile

Ukuze evamile ukusabela umzimba e pheshana emathunjini kudinga bokuphila ezithile kanye kwamakhemikhali uketshezi hepatic. Wena physiologically walungisiswa ukuchaza imisebenzi Bile e ukugaya uma imingcele yayo emitholampilo ijwayelekile. Bazimisele ngumuntu wamaqhuzu eziningi intubation duodenal.

Esigabeni sokuqala we lesifundo ingxenyenamba basal okulungele. Kufanele abe ukukhanya umbala ophuzi kanye pH mkhulu kunezinhliziyo 7. Esigabeni sesibili nge sphincter avaliwe Oddi imfihlo ivelele probe akufanele. In esigabeni sesithathu cwaningo amazinga emtholampilo ejwayelekile Bile zimi kanje: ivolumu - kusuka 3 kuya 5 ml, Umbala - ukukhanya brown. Isigaba sesine ihlala cishe ihora. Umbala uketshezi hepatic kuhluka omnqumo (Bile vesical) kuze ophuzi-Amber. pH layo = 6.5-7.5 kanye kwabantu of mayelana - 1038. Isigaba sokugcina, ukwabiwa Bile hepatic, ihlala afika kwangu-20. I kwabantu Sehlile 1011, pH = 7,5-8,2.

Ngeziphambeko kuzihlaka ngenhla kuyoba eyabonisa iziyaluyalu sokugembula kwesibindi, nenyongo sesinye noma mapayipi. Uhlobo oluvame kakhulu izifo kumiswa amatshe esinyeni ngenxa viscosity okwandisiwe uketshezi, kanye ukuhlukumeza contractile yayo umsebenzi. Njengoba ubona, kulesi sihloko sesibuyekeze futhi ngayifunda imfihlo yakho kwesibindi - Bile, incazelo kanye umsebenzi waso esikhathini esidlule kwaze izinqubo of kokudla esiswini.
