Bile umsebenzi e ukugaya

Bile - kuyimfihlo isibindi hepatocyte amaseli. It aqoqana Amapayipi encane Bile, bese engena imbobo ezivamile futhi ngokusebenzisa it - gallbladder 12 futhi duodenum. Imisebenzi isidumbu Bile ibalulekile. Omunye umsebenzi wayo obalulekile - ke ehilelekile izinqubo of kokudla esiswini.

Lapho Bile lilondolozwe?

Esinyeni nenyongo kuyinto tank isitoreji se-Bile. Phakathi isigaba asebenzayo of kokudla esiswini, uma ungaphandle esiswini phakathi duodenum 12 lwako kancane kugaywe ukudla, lapho lwabelwe senani esiphezulu. Imisebenzi esemqoka Bile womuntu - nengcenye ukugaya nqgo womsebenzi secretory motility emathunjini amancane, okuyinto kuqinisekisa ukucutshungulwa ukudla bolus.

Bile, okuyinto adedelwa ipheshana yesisu we gallbladder, ebizwa ngokuthi ovuthiwe futhi wadedelwa ngqo isibindi - abasha, noma isibindi.

Inqubo kanye excretion biliary of Bile

Inqubo yokwenza hepatocytes imfihlo (cholepoiesis) kwenzeka njalo. Bona kwenziwe uchungechunge zokuhlunga igazi izinto e-capillary Bile. Ngaphezu kwalokho, ngenxa reabsorption yamanzi nokumbiwa nosawoti isifika kumiswa lokugcina of the ukwakheka nokusaketshezi secretory. Le nqubo ibizwa lwenziwa Amapayipi Bile futhi gallbladder. Ingxenye Bile emathunjini agelezela ngokuqondile, ibizwa ngokuthi hepatic noma abasha. Kodwa isisindo salo esiyinhloko zanqwabelana esinyeni nenyongo, okuyinto ezinwabuzelayo Amapayipi Bile. Gallbladder Bile aqoqana, kuba uqweqwe kanzulu. Kuyinto mnyama ngaphezu kwesibindi.

Emini, amaseli sesibindi esingelapheki kubantu abangamaphesenti abadala ukukhiqiza mayelana ezimbili amalitha uketshezi. Ukuzila Ukudla-ke neze ingena emathunjini. Postprandial excretion biliary kwenzeka (holekinez) e 12-duodenum. Kukhona izenzo Bile njengoba wokugaya ukudla, kanye bacteriostatic kanye zokulawula. E. Inqubo kukodwa Regulator zokukhiqiza Bile futhi kukhuthaza biliary.

Ngakho, kulapho Bile acid adedelwa kwegazi portal (umthambo portal), ayanda ingqondo lichaza ekwakheni Bile futhi, ngokufanelekile, kancane kuhlelwe umqondo ngu hepatocytes. Imisebenzi ye-Bile futhi juice pancreatic ukugaya eziyisisekelo.

ukubunjwa Bile

Isakhi esiyinhloko Bile acid kukhona cholic. Iningi (67%) - a cholic acid chenodeoxycholic. I acid ezisele - yesibili, okungukuthi, okunye kwalezi acid ezimbili: deoxycholic, alloholievaya, lithocholic futhi ursodeoxycholic ...

Zonke acid Bile atholakala ngale mfihlo ngesimo compounds nge taurine kanye glycine. Okuqukethwe esiningi sodium ne-potassium ion ikunika ane-alikhali ukuphendula Bile.

Ngaphezu kwalokho, indlela yokwakheka Bile zihlanganisa ezinye izinto eziphilayo :

• Phospholipids.
• Amaphrotheni compounds, okungukuthi immunoglobulin, ayisiza A no M.
• Bilirubin futhi biliverdin (Bile zombala).
• Cholesterol.
• Mucin.
• Lecithin.

Futhi, ion of izinsimbi ezithile (zinc, ithusi, phambili, i-magnesium, indium mercury), amavithamini A, B, C.

Zonke izingxenye ngenhla ayingxenye futhi isibindi, gallbladder futhi Bile, kodwa imayelana 5 izikhathi ngaphansana ingqondo yokuqala kuka lesibili.

Bile umsebenzi

Bahlanganyela ezihlobene umsebenzi pheshana emathunjini. Bile umsebenzi e ukugaya elihlobene ne uchungechunge ukusabela enzymatic.

1. Ngosizo lwawo kukhona emulsification kwamafutha, ngaleyo ndlela kube lula ukumuncwa kwabo.
2. It neutralizes emiphumeleni elimazayo pepsin (juice esiswini ingxenye main), okuyinto okudiliza enzyme pancreatic.
3. Oyenza isebenze motility emathunjini amancane.
4. It ezizokhuthaza ukukhiqizwa kwamangqamuzana isikhwehlela.
5. Gastrointenstialnyh oyenza ekukhiqizweni kwama-hormone, secretin futhi cholecystokinin, okuyinto akhiqizwa amaseli emathunjini amancane kubuye kufake sandla ukulawulwa uketshezi kwamanyikwe.
6. Ivimba adhesion (adhesion) amagciwane athile kanye izingxenye proteinaceous.
7. It has an umphumela isinqandakuvunda ku amathumbu ehilelekile kumiswa indle.

Ngakho, umsebenzi we Bile e ukugaya ayikwazi babenesibindi esikhulu. Kuyinto ngenxa inqubo Bile wokugaya ukudla, kuqalile esiswini, uyaqhubeka futhi iphela emathunjini ngokuphepha.

Bile Inani umzimba womuntu

Ngakho, sathola ukuthi umsebenzi oyinhloko Bile elihlobene ne inqubo wokugaya ukudla. Kwenzekani uma, ngasizathu simbe, ukushintsha ukwakheka Bile noma engawuboni ufake ipheshana wokugaya ukudla? Ukushoda noma ukungamthandi kwakhe kuholela pathologies sina:

• Cholelithiasis.
• Steatorrhea.
• Gastroesophageal Reflux isifo (Gerd), kanye nabanye.

cholelithiasis

Lokhu zokugula kungenzeka ngenxa Ukwakheka ofanele Bile. Lokhu kubizwa ngokuthi yi Bile lithogenic. izakhiwo ezinjalo kungase ukuthola phakathi amaphutha avamile ekudleni, okungukuthi uma ukudla ubuswa ezilwane. isibindi Bile imisebenzi kungenzeka kahle ngenxa izifo endocrine. Ngaphezu kwalokho, izakhiwo lithogenic we uketshezi hepatic zingase zithole ngenxa iziyaluyalu lipid umzimba, okuyinto ngokuvamile uhambisana ukwanda isisindo emzimbeni. Isizathu ukuze izinguquko of Bile Ukwakheka kungaba ukulimala ezithathelwanayo futhi ezinobuthi isibindi noma yokuphila insufficiently asebenzayo (ukungawuvivinyi umzimba).

stearrhea

Njengoba kushiwo ngenhla, imisebenzi ephathelene ne-Bile emulsification kwamafutha. Uma ngasizathu simbe Bile iyeke iyangena emathunjini amancane ukuncela amafutha kungenzeki, ngaleso sikhatsi bafundza bacala wehluke indle. Kungenzeka okufanayo nge ukuntula ku uketshezi hepatic of Bile acid (ushintsho ngezithako zawo). Kulokhu, ngemva kwalokho angene endleni iba ukungaguquguquki omhlophe noma mpunga bese okunamafutha. Lokhu zokugula libizwa steatorrhea. Nalesi sifo, umzimba akanayo amafutha abalulekile ngokwanele, acid okunamafutha futhi abanye amavithamini. Ngenxa steatorrhea ahlupheke wamathumbu ephansi, t. Ukuze. Kungukuthi bazivumelanisa chyme ezinjalo.

Kanjani ukuba sihlole Bile?

Ukuze siphenye isakhiwo kanye umsebenzi Bile, wasebenzisa abaningi indlela wamaqhuzu intubation duodenal. Le nqubo siqukethe izinyathelo emihlanu:

1. uketshezi Basal of Bile - kuyinto ukwabiwa ezivamile Bile imbobo 12 uketshezi kanye isilonda duodenal. Uthatha imizuzu engu-15.
2. Secretory isigaba ukumisa okwesikhashana noma sphincter avaliwe Oddi. Isikhathi salesi simiswe imizuzu 3.
3. Isigaba ngokuhlukana we asalile ingxenye A. Bile ihlala cishe imizuzu engu-5.
4. Isigaba ngokuhlukana gallbladder Bile izingxenye B. Le nkathi ihlala cishe imizuzu engu-30.
5. Kwemihlambi Bile hepatic - ingxenye S. Lesi sigaba ihlala cishe 20 imizuzu.

Ngakho, ingxenye 3 Bile. Bonke bangabangasokile ezahlukene kwengoma. I kanzulu kakhulu Bile vesical - ingxenye B. Iqukethe inani elikhulu-fatty acid, bilirubin, kanye nezinye izingxenye Bile.

Le ndlela ivumela cwaningo ukucacisa Izakhiwo zanoma Bile, ukubunjwa yayo, inani esinyeni inyongo isimo ipheshana biliary , futhi ukukhomba kwasendaweni yenqubo sokugembula.
