Ke kūlana o ka bile ma digestion. E wehewehe i ka hana o ka bile ma digestion

E ka i aku nei au, ma mua oe i ka mea e hiki mai ana hana: e wehewehe i bile kuleana pili i ka digestion. E hana i kēia, e pono mua hoʻopaʻa haʻawina kona biochemical haku mele 'ana, ka waiwai a me maomeka o ka bile e pono ai no ka pono digestion o ke aloha' ona mea e mai i ka ai. Mau nīnūnē e e hōʻike 'ia ma kēia' atikala.

secretory kuleana pili i

Ke akepaa o ka nui loa gland i loko o ka gastrointestinal'āpana, hoʻomaopop 'ana i loko o vertebrate holoholona a me ke kanaka. Ua ninoieo o parenchymal keena, kapaʻia hepatocytes. A hookahi hepatic halepaahao i kekahi a oi nuclei, a he o māhele mau kapaia vascular a me ka biliary. Hope aoao hepatocyte hui 'ana me sinusoids i loaa ke koko mai ka hepatic aa koko. Keia hapa synthesizes monakō koko, nā polokina, nā wikamina a me lipocomplexes.

ʻO kekahiʻaoʻao o ka hepatocyte olelo ma bile capillary. Ua Ua kapaia biliary. Ua produces bile. Ua kahe aku i loko o ka capillary, a mai ia - i loko o ka ducts. Pela, i ola ake bile ua loaʻa hepatocyteʻaoʻao, aole ia e komo i ke koko, no ka biliary capillary ua kaawale mai ke kino mai o hepatic sinusoidal keena.

It E e kaulana ia e Hoʻohui 'na hepatocytes e lilo Hoʻohana, no a ka bile ducts ma a me ka mai. Ka mea, merge a me ke ano mau papa kuhikuhiEʻaoʻao - haʻalele a me ka pololei. Ka mea, i hele mai mai loko mai o na kikowaena lobe o ke akepaʻa. A laila, merge e lilo i kekahi e like me ka leki uea i kŰlń ao mai kona puka a me ka vpadot i loko o ka gallbladder. Pela, ke akepaʻa o ka hui, pee bile. Anatomia o ka bile, au bladder 'ole a me ka hana, e manaoia e mai no hoi ia.

I pono i ke kala o ka bile?

Hui e kōkua pili aku macromolecule luna 'ke aloha eiiiiiaiou o ka ai, bile pili. Ua hana ma ka sighting lipids, hoʻololi 'ia, mai ka insoluble moku'āina e lilo i emulsion. Paa ana ma ka bile nāʻakika cholic - chenodeoxycholic a me ka cholic - i ili-hana 'ona. Ka mea, emulsify mea momona ka ai i loaa mai ka'ōpū i loko o ka duodenum, e pono ai kā lākou splitting ua ua hoʻololiʻia ma nā'ūhū o na pancreas - lipase.

Ke biochemical haku mele 'ana o ka bile

Ike i ka 'ole o ka mall hehee wale o ka hepatic lobes, māhele o biliary hepatocytes, e like me ka biochemical haku mele' ana, e ua pono wehewehe i ka hana o ka bile ma digestion. Gastroenterologists, ua loaʻa i loko o ke akepaʻa ka luna 'keʻano o ka hanaʻana o ke ea kahe a me ka ikehu pūnao. Bile iho o ke kinowai a mālamalama oliva mea eleele. Ua be 98% wai, me ka pono me pigments, naʻokoko, cholicʻakika, lecithin, nā wikamina a me nā'ūhū.

E noonoo oe i ka 'ole a me ka holo o ka bile nāʻakika. Ka mea i hana mai i ka steroid ka waiʻona - naʻokoko. He mea i kekahi hapa o ka halepaahao membranes. Ma hepatocytes naʻokoko ua oxidized, a hana i ka iniiaiie bile nāʻakika. Ka mea, hiki mutate, e lilo ana kiʻekiʻe: metaholevuyu a me ka deoxycholic. Ka poe, ma ka huli, kuahene eiiieaenu me ka kumuʻiʻo monomers - taurine a me ka glycine.

Mau pono a pau o nō ka loa kū'ē, a i na i loko o ka wai i loko o ka palapala o ka paʻakai a potasiuma paʻakai. Bile pigments - kekahi biochemical ke keʻena, i ka papa kuhikuhi o ka i mea bilirubin. Ua ua hana ma o ka make ana o ka hemoglobin i ia lŘlŘ ma ke akepaʻa macrophages - Kupffer keena e like me ia ma ka spleen. Lecithin - he ke keʻena o ka bile. Ua ua no hoi i hanaʻia i loko o ke ake, a Radio nui i kūlana ma ka pūnao o momoma nāʻakika a me ka naʻokoko hakumakuma konaʻilikai. He kekahi mea i loko o ka emulsification o kona kaikea a hapa.

He aha ka waiwai o ka bile?

E aʻo i ka Nine Inch haku mele 'ana o nā secretions o ke akepaʻa, hiki ho i pololei kona kūlana i loko o ka hālāwai hope o ke aloha a me ka mea, e noonoo i ka walaʻauʻana mana o ka bile ma digestion, a i ka nohona. No ka laʻana, inā loaʻa he detergent a me kaʻakika ka hoʻopukaʻana i ka momona, splitting nui nā lātoma i loko o liʻiliʻi poʻe. Bile e loli ai na nā'ūhū hydrolyze na carbohydrates a me nā polokina: amylase a me ka trypsin, mahuahua ko lakou catalytic waiwai. Ma gastric'ūhū - pepsin - ka mea hana i ke ku pono ana i alanui, a laila inhibits kona haʻawina, i hiki aku ai i ka pahikaua mahuahua ma ka pH o gastric Contents, mahope mai o kaʻakika emi.

Hoʻokaʻawale o ka bile hoʻokāʻoi aʻe ana i omo pāʻoihana o ka mea pōhaku paʻakai, no nā wikamina A a me D, e like me'amino nāʻakika. Ka ike ole ia o ke akepaʻa regulates ka Hawaii a me ka secretory hana o ka uuku liʻiliʻi. 'O kēia ke kūlana o ka bile ma digestion.

Maomeka o ka bile a me ka zholcheotdeleniya

Mua, ua aʻo mākou i ka waiwai o ke akepaʻa secretion hua mai ma biliary māhele o hepatocytes. A i loaʻa mākou i ka haku mele 'ana, ka waiwai o ka bile a me kona nui i loko o digestion interrelated. i lawe mai kēia mau maomeka nā kanaka ko mākou hopohopo'ōnaehana a me humoral ala. bile ho okumu ua hoʻokāʻoi 'like me ka reflex pane e stimulation interoceptors paia mucous membranes o ka moʻolelo lua, opu, naʻau liʻiliʻi.

Gallbladder: kona 'ole a me ka kūlana ma ka digestion

E like me ka mea muscular hui, ka mea, ua aia ma lalo o ka haahaa kae o ke akepaʻa. He He He'ā'ī, kino a me lalo. Once oe anatomically obosnueteʻano papa hana o ka hana, a laila, e hiki wawe ka wehewehe i ka hana o ka bile ma digestion. I ua mau ho okumu i loko o ke ake, a hookuu i loko o ka duodenum pono i loko o ka manawa o ke komo i loko o ka meaʻai kino. Ma waena oʻai huna waihoia ma ka gallbladder.

No ka maʻamau metabolic reactions ma ka gastrointestinal'āpana koi kekahi physiological a biochemical hepatic secretion. Oe i physiologically hoaponoia mai nei kakou e wehewehe i ka mana o ka bile ma digestion ina kona lapaʻau kiko'î mea maʻamau. Ka mea i hoʻoholo 'ia e ka nui fractional duodenal intubation.

Ma ka pae mua o ke ao ua makaukau oia i ka basal mahele. It e i ka malamalama melemele waihoʻoluʻu a me ka pH oi aku 7. I ka lua o ka pae a me ka paʻa sphincter o Oddi malu ke ku mai, mai kaʻimi e ole. Ma ke kolu o ke kahua o ke ao clinically mahana maʻamau o ka bile e like penei: ka leo - mai ka 3 a hiki i 5 ml, Waihoʻoluʻu - malamalama eleele. I ka ha o ka pae mau e pili ana i ka hora.
