Ubonelelo igazi ebuchotsheni, isibindi nezintso

Eli nqaku lichaza ezinye bokuqonda igazi ubonelelo nezibilini ezibalulekileyo ezifana ingqondo, isibindi kunye nezintso.

ukugeleza kwegazi Cerebral

igazi flow Isimbuku ingqondo njalo, yaye amandla liphezulu ngokwaneleyo. Njengoko kuba ligazi ukuhamba basekuhlaleni kwiindawo ezahlukeneyo ingqondo, oko kumiselwa ubunzulu umsebenzi wabo. Ngenxa yoko, xa umsebenzi oqobayo lendawo igazi ebuchotsheni ngamandlakazi wayo kwandisa ezimbini ukuya kuthelekiswa kathathu ubunzulu ukuhamba kwegazi ukuphumla.

Ngokwemiqathango ukuqina kunye yengxinano kwabantu ukhakhayi ukumelana iyonke iinqanawa yobuchopho ukuya kwiqondo encinane ixhomekeke utshintsho wegazi. Ngoko, xa uxinzelelo kwi imithambo kwenzeka ukwanda labo, nto leyo yandisa yengcinezelo utywala, kwisisu yayo lokuphuma ngemithambo cord ucinezelo umnqonqo. Ngelo lixa ukuhla ukunganyangeki esimbaxa nokunyusa ukumelana lwemithambo. Ngaloo ndlela, kwa oku komelela ebuchotsheni nemithambo, ngokubanzi, ihleli phantse ingatshintshanga.

ukusebenza Myogenic flow igazi ebuchotsheni lukhutshwe ngayo esihlunwini kakuhle imithambo yegazi yobuchopho kutshintsho xi kubo. Libhekisela kwinkqubo autoregulyatsionnoy unit central kwegazi lobuchopho.

Esinamandla ebuchotsheni isilawuli flow kwegazi ngazo kwinqanaba ombane of igazi esimbaxa carbon dioxide kunye enxulumene inqanaba pH ulwelo fluid.

neziphumo umzimba flow igazi ebuchotsheni kubalulekile ukuba ngokutsha yendawo yokumpompoza kwegazi phakathi kwiindawo ingqondo, apho umsebenzi ezisebenzayo imeko ngamnye inqanaba eyahlukileyo. Ekwandeni bengingqi umsebenzi esebenza ngayo iiseli zemithambo kwi extracellular medium kwandisa lwee- ion potassium kunye adenosine. Oku kubangela ukukhula yendawo nemithambo kunye nokwanda kwegazi kwimikhumbi.

ukusebenza Neurogenic flow igazi ebuchotsheni zithathwa ukuba abe ngaphantsi kwe-ummiselo metabolic olusebenzayo. Eyona ndawo iphambili kwesicelo yi ariya iimpahla esimbaxa yobuchopho, ubudeki 25-30 microns. Umthombo ezingundoqo neziphumo neurogenic flow igazi ebuchotsheni zithathwa novelwano postganlionarnye nefayibha. ummiselo ubukhulu becala ukoyika binzana kuxhomekeke autoregulyatsionnoy ombane O2 kunye CO2, eqala nemithambo ithoni, ingqondo kunye nolwakhiwo ion, kwaye kananjalo kubukho cerebrospinal kunye isicwili sobuchopho izinto eziphilayo esebenzayo fluid.

ubonelelo yegazi esibindini

Ekungeneni ngesango hepatic isibindi Umthambo kunye umthambo, na ulwahlulo zazo ezityeni ezininzi ezincinane, ehamba kulo lonke bile duct. Umthambo Interlobular kunye umthambo kunye duct interlobular interlobular bobabo kuthiwa-"isibindi triad." iindawo nkovu elise ekufutshane. Ukusuka vokrugdolkovyh emithanjeni ngemithambo emithanjeni kumka khangela lobules hepatic nokuhlanganisa kwi sikwi zabo, ukwakha izitya intralobular. Ngokutsho kuye igazi ubaleka imigqakhwe kwicala ziqwempu iziko ukususela kwimida kwaye iqokelelwe kwi Ebhekisa kwinto esembindini, iqala nge-krovoottok inezilayo emithanjeni sublobular, ezenza imithambo hepatic ezinkulu eshiya.

kidney igazi

Umthambo, ilungu lomzimba yesango ihlukane yegazi, disintegrating, ke, phezu kwemithambo interlobar. Xa umda uthinte kunye Medulla, awugqithe kungena kwemithambo ngokwandisa arcuately kwaye ingqamene phezu sezintso. Ukusuka kule mithambo kushiya inani elikhulu ezincinane ezingcakacileyo interlobular, leyo amele kumphezulu emzimbeni. Perfusion Medulla sezintso wathwala arterioles ngqo, imithambo elandisiweyo ukususela arc. Mfutshane amasebe zisecaleni kwemithambo interlobular ziyinxalenye philisi glomerular. It amasebe Kwathi kungena kuthungelwano capillary. Emva koko Ukumanyanisa emithanjeni emithanjeni kwaye ukuyilwa arterioles efferent.
