Basa bile mu kugaya. Rondedzera kushanda bile ari kugaya

Toti, usati isa inotevera basa: tsanangura bile basa iri kugaya. Kuti aite izvi, unofanira kutanga kudzidza kwayo nokukanganisika sezvamunoita, zvivako uye zvigadziriswe pakati bile zvinodiwa zvakakodzera kugayiwa Organic zvinhu anoumba chikafu. nyaya idzi zvichakurukurwa kugadziriswa munyaya ino.

secretory basa

Chiropa ndicho chikamu chikuru shwanu iri nemudumbu, tinoberekwa mhuka vertebrate uye murume. Inoitwa parenchymal masero, inonzi hepatocytes. A sero chete hepatic ane kana kupfuura nuclei uye ine zvikamu zviviri anonzi vascular uye biliary. Last bato hepatocyte kuonana sinusoids vanogamuchira ropa kubva hepatic mutsinga. Chikamu ichi synthesizes shuga, mapuroteni, mavhitaminzi, uye lipocomplexes.

The mhiri hepatocyte akarayira akananga bile rirambe richibvira. Inonzi biliary. Unobereka bile. Inoyerera kure mukati rirambe richibvira, uye pairi - iri ducts. Saka, muna utano chiropa bile wakadenha divi hepatocyte asingadi kupinda muropa, sezvo biliary rirambe richibvira anosiiwa pamuviri sinusoidal masero hepatic.

Zvinofanira kucherechedzwa kuti hepatocytes dzikarongwa kutanga zvikamu, iyo bile ducts nokubuda. Ivo batanidza uye chimiro mbiri huru mirayiridzo - kurudyi. Ivo vanobuda nechepakati akafukidza chiropa. Zvino batanidza kuumba chakajairika mutsinga dzinofamba nemukaka iyo rinoenderera gedhi racho uye vpadot zviri pasi gallbladder. Saka, chiropa ndiyo nhengo secreting bile. Anatomy pamusoro bile, nduru dundira mamiriro uye mashandiro ichakurukurwa nesu mberi.

Kunoda kusunungurwa bile?

Yeimwe chinobatsira makanamatira macromolecule kunzwisisa Organic zvinoumba zvokudya, bile anorondedzera. It chiito sighting lipids, vachichinja navo kubva insoluble ehurumende iumbe emulsion. Kuitwawo bile acids cholic - chenodeoxycholic uye cholic - zviri pamusoro-basa zvinhu. Ivo emulsify mafuta zvokudya kubva mudumbu kupinda duodenum, kufambisa kukamurwa kwavo kwakaitwa makemikari ose rwatata - lipase.

The nokukanganisika Zvinoumba bile

Kuziva nemamiriro STRUCTURAL pezvokuvamba hepatic lobes, zvikamu biliary hepatocytes, uyewo nokukanganisika nziyo, imi zvakarurama kutsanangura mashandiro bile mu kugaya. Gastroenterologists rawanikwa kuti chiropa kuoma dzinotsanagura epurasitiki iyerere uye simba muviri. Bile pachayo imvura kana chiedza muorivhi mashava. Rine 98% mvura, uyewo pigments, remafuta akawandisa, cholic acid, lecithin, mavhitaminzi uye makemikari.

Funga mamiriro uye kuparadzirwa pakati bile acids. Vari aumba kubva steroid doro - remafuta akawandisa. Iyewo chikamu muchitokisi membranes. In hepatocytes remafuta akawandisa ari oxidized uye kuumba chikuru bile acids. Vanogona mutate, vachiva yechipiri: metaholevuyu uye deoxycholic. Avo, akavapindurawo, anoumba zvivako pamwe mapuroteni monomers - taurine uye glycine.

zvivako ava kupfuura reactive uye huri mvura iri chimiro yavaibvisa kana potassium munyu. Bile pigments - mumwe rokuti nemakemikari, chikuru chiri bilirubin. Zvinonzi inoumbwa kuparadzwa Chizenga kunoitika muna chiropa macrophages - Kupffer masero uyewo ari chirwatata. Lecithin - chimwe chezvinonhuwira bile. Chinonziwo kuumbwa mune chiropa uye inoita basa rinokosha iri muviri womunhu mafuta acids uye remafuta akawandisa richikwidibira ayo mwero. Iyewo anotora rutivi mune emulsification kwemafuta.

Zvinotaurwa ehupfumi kuti bile?

Zvaakanga kudzidza makemikari anoumba secretions chiropa, anogona zvakarurama kumiririra basa yaro kuparara makemikari nyaya uye kuti kufunga inokosha bile mashandiro ari kugaya, izvo siyana. Somuenzaniso, rine sipo uye asidhi kuita mafuta kukamurwa mamorekuru guru kupinda madiki vavo. Bile kunokanganisa makemikari hydrolyze kuti makabhohaidhiretsi uye mapuroteni: amylase uye trypsin, vachiwedzera CATALYTIC ehupfumi dzavo. In gastric enzayemu - pepsin - nayo chiito zvevakomana nzira, i.e. kuchititadzisa kwayakaita, iyo inosvitsa unopinza kuwedzera ph pamusoro gastric mukati, sezvo acidity kunoderedza.

Voga kuti bile kunonatsiridza Absorção de Água kugadzirisa zviri chicherwa munyu, mavhitamini A uye D, uyewo amino acids. Chakavanzika chiropa anoita injini uye secretory kushanda ura duku. Ndiro basa bile mu kugaya.

Zvigadziriswe pakati bile uye zholcheotdeleniya

Kare, tadzidza ehupfumi chiropa secretion zvinoberekwa biliary zvikamu hepatocytes. Uye nesuwo akawana kuti murwiyo, zvivako zviri bile wayo kukosha mune kugaya zvinodyidzana. zvigadziriswe iyi yaitwa vaviri dzevanhu tsinga uye humoral nzira. bile inotungamirwa kunosimudzirwa sezvo dzepanguva mhinduro dzishande interoceptors masvingo mucous membranes ari nomumukanwa mhango, dumbu, ura diki.

Gallbladder: kwayo marongerwo uye basa kugaya

Sezvo tsandanyama nhengo, riri pazasi yepazasi kumucheto chiropa. It ane mutsipa, muviri uye pasi. Kamwe iwe anatomically obosnuete mashandiro basa rayo, zvino unogona kutsanangura mashandiro bile nyore kugaya. Achingogaroudzwa dzichiumbwa chiropa uye akabudiswa mugomba duodenum chete panguva kubvuma kupinda mumuviri zvokudya. Between kudya chakavanzika iiswe gallbladder.

Chirwere nzira kuongorora kuti bile

Nokuti kuipa metabolic chinja ari nemudumbu zvinoda vamwe vasiri uye nokukanganisika hepatic secretion. Muri physiologically anoruramiswa kutsanangura mashandiro anoita bile mu kugaya kana zvayo kurapwa parameters vari muupenyu. Vakatsunga ne vakawanda fractional duodenal intubation.

In wokutanga chokutambudzika chidzidzo basal hacho akanga akagadzirira. Inofanira kuva chiedza yero ruvara uye ph kupfuura 7. yechipiri danho ane namahwindo sphincter pamusoro oddi zvakavanzika kumira kubva vachiongorora havafanire. In wechitatu pavaipfuura kudzidza akaora chakaipa kwevari bile ndeinotevera: vhoriyamu - kubva 3 kusvika 5 Rine mamiririta, Color - chiedza mashava. Wechina danho rinovapo inenge awa. Color hepatic secretion dzinosiyana emiorivhi (vesical bile) kusvikira yeyero-rinopenya. ph Its = 6.5-7.5 uye arambe achirema vanenge - 1038. The wokupedzisira chokutambudzika, kuti hurumende ichiisa hepatic bile, huchavapo kusvika maminitsi 20. The arambe achirema zvinoderedza kusvika 1011, ph = 7,5-8,2.

Zvarakasiya kubva pamusoro parameters vachava anoratidza pathological kusagadzikana chiropa, nduru dundira kana ducts. Vakawanda Chirwere nokuumbwa matombo dundira nokuda vawedzere viscosity yacho fluid uyewo kukanganisa kwaro contractile chaitika. Sezvaunogona kuona, munyaya ino isu akaongororwa uye akadzidza chakavanzika chiropa - bile, chinangwa chacho basa iri dzinotsanagura kugaya.
