Uyazi ngalo mthambo wegazi omangalisayo oya esibindini? (I-Portal Vein) Ake sixoxe ngalokhu!

Wake wacabanga ngemithambo yegazi engaphakathi emizimbeni yethu? Cishe awukaze ucabange ngayo kangako, akunjalo? Kodwa, namuhla sizokhuluma ngomthambo wegazi obaluleke kakhulu futhi okhethekile emizimbeni yethu. Lokhu kubizwa ngokuthi i-Portal Vein . Uma sikhuluma ngokuqondile, lokhu kufana nomgwaqo omkhulu othwala igazi lisuka ezithweni eziningana ngaphakathi esiswini sethu liye esibindini.

Iyini le portal vein?

Kalula nje, umthambo wakho we-portal uwumthambo wegazi othwala igazi lisuka ezithweni eziningi esiswini sakho uliyise esibindini sakho. Isibindi sakho sibe sesihlanza leli gazi, silihlunge, silicubungule, bese silibuyisela enhliziyweni yakho. Ukusuka lapho, igazi liphampunwa kuwo wonke umzimba wakho.

Ngokuvamile, njengoba sazi, imithambo yegazi ithwala igazi iye enhliziyweni. Kodwa-ke, imizimba yethu inesimiso esikhethekile esibizwa ngokuthi i-Hepatic Portal System noma i-Portal Venous System . Lokhu kuhluke kancane ohlelweni olujwayelekile. Imithambo yegazi kulesi simiso ayithwali igazi ngqo enhliziyweni, kodwa iya esibindini. Umthambo wegazi oyinhloko kulolo hlelo yi- Portal Vein .

Ukuze uqonde lokhu, cabanga ngakho "njengomzila womgodi" emzileni womjaho. Lo mthambo wesango uyindlela eya esibindini. Isibindi sifana "nendawo yokuma emgodini" lapho igazi lenza khona "ukulungiswa" okudingekayo.

Uma igazi lingena emthanjeni we-portal, ligcwele izakhamzimba umzimba wethu okudingeka uzicubungule ngaphambi kokuba uzisebenzise. Liphinde liqukethe ubuthi , okuyizinto eziyingozi umzimba ongazidingi. Ngakho isibindi "siyalungisa" leli gazi. Okusho ukuthi, liguqula izakhamzimba zibe uhlobo umzimba ongalusebenzisa ngokushesha noma oluzolugcina. Ngesikhathi esifanayo, lisusa ubuthi.

Ngemva kwalokhu "kulungiselelwa," igazi lisuke selilungele ukubuyela enhliziyweni. Ngakho-ke, liphuma esibindini bese lijoyina umthambo omkhulu obizwa ngokuthi i-Inferior Vena Cava , lapho liya khona ekamelweni eliphezulu kwesokudla senhliziyo, i-Right Atrium .

Uyini umsebenzi we-Portal Vein?

Umsebenzi oyinhloko womthambo wakho we-portal ukuthwala igazi lisuka ezithweni ezisesiswini sakho liye esibindini sakho ukuze licutshungulwe. Ngakho-ke, kubalulekile ohlelweni lwe-portal venous. Luwumnyango oyinhloko wegazi ukungena esibindini. Yonke eminye imithambo emincane ekugcineni ihlangana futhi ixhumane nalo mthambo we-portal. Ngakho-ke, ukuze lonke uhlelo lusebenze kahle, lo mthambo we-portal udinga ukuba nempilo enhle futhi usebenze kahle.

Imisele eletha igazi emthanjeni we-portal

Kunezinhlobo eziningana zamagatsha ahlinzeka ngegazi emthanjeni we-portal, okungukuthi, ayawujoyina. Lawa angama:

• Umthambo we-Mesenteric Ophakeme (SMV): Lo mthambo uthwala igazi elivela ezithweni eziningana eziphakathi kwesisu sakho, ikakhulukazi amathumbu akho amancane.
• Umthambo we-splenic:Lokhu kudonsela igazi ebhodweni lakho.
• Umthambo we-Mesenteric ophansi: Lo mthambo uthwala igazi elivela ezingxenyeni zamathumbu akho amakhulu.
• Imithambo Yesisu: Le ithwala igazi lisuka esiswini sakho.
• Imithambo Yesicanucanu: Le ithwala igazi elivela enyongweni yakho.

Igazi eliqoqwe kuyo yonke le mithambo liya esibindini ngomthambo wesango.

Ikuphi le portal vein?

Umthambo wakho we-portal uqala ngemuva nje kwentamo ye -pancreas yakho naphambi kwe -inferior vena cava yakho. Ukusuka lapho, udlulela endaweni ebizwa ngokuthi i-porta hepatis , noma i-liver hilum. Le porta iyindawo lapho imithambo yegazi nezinye izakhiwo zingena futhi ziphume khona esibindini.

Iyini isakhiwo somthambo we-portal?

Umthambo wakho we-portal wakheka lapho umthambo wakho we-mesenteric ophakeme (i-SMV) kanye nomthambo we-splenic uhlangana khona. Ukusuka lapho, umthambo we-portal uhamba uye phezulu uye kwesokudla, ngemuva komthambo wakho wesibindi , uze ufike esibindini.

Njengoba ingena esibindini, umthambo wakho we-portal uhlukana ube amagatsha amabili. Lawa yi -Left Portal Vein yakho kanye ne -Right Portal Vein yakho. Lawa magatsha ahlukana abe amagatsha amancane aya ezingxenyeni ezahlukene zesibindi.

Izinguquko ku-Anatomy

Ngezinye izikhathi, izinguquko ezincane kulesi sakhiwo zingabonakala. Enye yezinguquko ezivame kakhulu ibizwa ngokuthi i-portal vein trifurcation . Yilapho i-portal vein ihlukana khona ibe amagatsha amathathu esikhundleni samabili njengoba ingena esibindini. Lawa magatsha yilawa:

• Umthambo Wesango Lesobunxele
• Umthambo Wesango Elingaphambili Lesokudla
• Umthambo Wesango Langemuva Lesokudla

Lolu shintsho aluyona ingozi. Kodwa-ke, kubalulekile ukwazisa udokotela wakho ngalo ngaphambi kokuhlinzwa okuthile kanye nezinqubo ezithile zezokwelapha. Odokotela bazokwenza izivivinyo zezithombe ngaphambi kokuhlinzwa ukuze bafunde ngesakhiwo somzimba wakho bese beshintsha inqubo yokuhlinzwa njengoba kudingeka.

Ingakanani i-portal vein?

Ngokuvamile, umthambo wakho we-portal ungamasentimitha angu-8 ubude futhi ungadluli kumamilimitha angu-13 ububanzi.
