Singakhuluma nje ngemithambo yegazi emizimbeni yethu: Imithambo yegazi kanye nemithambo yegazi?

Wake wazibuza ukuthi leli gazi ligeleza kanjani liye phambili nangaphakathi emizimbeni yethu? Cabanga nje, njengemigwaqo edolobheni elikhulu, imizimba yethu nayo inesimiso esikhethekile semigwaqo yokuthwala igazi. Le migwaqo ibizwa ngokuthi imithambo yegazi nemithambo yegazi, ebaluleke kakhulu empilweni yethu nasempilweni yethu. Ngakho-ke namuhla, ake sixoxe kalula ngokuthi le mithambo yegazi nemithambo yegazi iyini, ukuthi ibaluleke kangakanani emizimbeni yethu, nokuthi yini esingayenza ukuze siyigcine iphilile.

Iyini le 'ndlela yegazi' emizimbeni yethu? (Uhlelo Lokujikeleza Kwegazi)

Kalula nje, lokhu sikubiza ngokuthi uhlelo lokujikeleza kwegazi . Lokhu kufana 'nensizakalo yezokuthutha' enamandla kakhulu emzimbeni wethu. 'Injini' eyinhloko yale nsizakalo inhliziyo yethu. Igazi elimpontshwa yinhliziyo lihamba emzimbeni wonke 'ngemigwaqo' ebizwa ngokuthi imithambo yegazi nemithambo yegazi.

Cabanga ngakho, leli gazi yilo elithwala umoya-mpilo nezakhamzimba ezidingwa yiwo wonke amaseli emzimbeni wethu, njengokuletha ukudla ekhaya. Futhi, le 'mithambo yegazi' ithwala nemikhiqizo engafuneki ekhiqizwa amaseli, njenge- carbon dioxide . Ngakho-ke manje uyabona ukuthi kubaluleke kangakanani ukuthi lolu hlelo lusebenze kahle, akunjalo?

Iyini imithambo yegazi? – ‘Imigwaqo emikhulu’ egijima isuka enhliziyweni kuwo wonke umzimba

Kulungile, ake siqale sibheke ukuthi iyini imithambo yegazi. Kalula nje, imithambo yegazi iyimithambo yegazi ethwala igazi elihlanzekile, elinomoya-mpilo lisuka enhliziyweni liye kuzo zonke izingxenye zomzimba (ngaphandle komthambo owodwa okhethekile, esizokhuluma ngawo kamuva). Ifana 'nemigwaqo emikhulu' yedolobha, ethwala igazi lisuka 'enkabeni yedolobha', inhliziyo, ngesivinini esikhulu. Igazi elisemithambo yegazi livame ukuba bomvu ngoba linomoya-mpilo omningi.

Izindonga zale mithambo yegazi zijiyile futhi zinamandla kunezemithambo yegazi. Lokhu kungenxa yokuthi kufanele zimelane nomfutho ophezulu odalwa yinhliziyo ipompa igazi. Cabanga ngakho njengepayipi elithwala amanzi lisuka ethangini lamanzi. Umthambo omkhulu emzimbeni wethu yi -aorta . Yilapho igazi lisakazwa khona kweminye imithambo yegazi emincane, ebizwa ngokuthi ama-arterioles .

Kuthiwani uma unezinkinga ngemithambo yakho yegazi?

Kodwa-ke, ngisho nale 'migwaqo emikhulu' ingaba nezinkinga. Inkinga enkulu ukuqina nokuncipha kwezindonga zemithambo yegazi, okwaziwa ngokuthi i-atherosclerosis . Lokhu kwenzeka lapho i-cholesterol namafutha angafuneki avela ekudleni esikudlayo enqwabelana emithanjeni yegazi njenge -'plaque' , okuvimbela ukugeleza kwegazi. Kufana nokugqwala okwakhela ngaphakathi kwepayipi lamanzi elidala.

Kwenzekani uma lokhu kwenzeka? Imithambo yegazi ehambisa igazi enhliziyweni (ebizwa ngokuthi imithambo yegazi yenhliziyo ) ingavaleka, okubangela ukuhlaselwa yinhliziyo . Uma imithambo yegazi ethwala igazi ebuchosheni ivaleka, okubangela isifo sohlangothi , kungabangela nomfutho wegazi ophakeme .Imithambo yegazi nayo ingalimala. Ngezinye izikhathi udonga lwemithambo yegazi lungabuthakathaka futhi luvuvuke njengebhaluni, esikubiza ngokuthi i-aneurysm . Ukuze uvimbele konke lokhu, udinga ukugcina imithambo yegazi yakho iphilile.

Iyini imithambo yegazi? – ‘Izindlela zokubuyela’ kusukela emzimbeni kuya enhliziyweni

Manje ake sixoxe ngemithambo. Imithambo ifana 'nemigwaqo yokubuyela' eqoqa futhi ithwale igazi elingenawo umoya-mpilo, elicebile nge-carbon dioxide lisuka ezingxenyeni ezahlukene zomzimba (ngaphandle komthambo owodwa okhethekile) libuyele enhliziyweni. Lena yimithambo ebukeka iluhlaza okwesibhakabhaka ngaphansi kwesikhumba sakho. (Ayibukeki iluhlaza okwesibhakabhaka ngoba igazi liluhlaza okwesibhakabhaka, kodwa ngenxa yendlela ukukhanya okudlula ngayo egazini elingenawo umoya-mpilo kanye nesikhumba).

Izindonga zemithambo zincane kancane kunezemithambo. Lokhu kungenxa yokuthi igazi ligeleza ngemithambo ngengcindezi ephansi kunemithambo. Enye yezinto ezikhethekile ngemithambo ukuthi inama-valve . Lawa afana neminyango evula indlela eyodwa kuphela. Lawa ma-valve asiza ekuvimbeleni igazi ukuthi lingaphindeli phansi, ikakhulukazi uma kukhulunywa ngegazi elibuya emilenzeni liye enhliziyweni. Ngaphandle kwalokho, amandla adonsela phansi angabangela ukuthi lonke igazi ligeleze phansi! Imithambo emibili eyinhloko eqoqa igazi ezingxenyeni eziphezulu nezingezansi zomzimba wethu bese ilibuyisela enhliziyweni yi -Superior Vena Cava kanye ne-Inferior Vena Cava . Imithambo emincane exhuma kulezi ibizwa ngokuthi ama-venule .

Izinkinga zemithambo yegazi

Ezinye izinkinga zingase zivele nasemithanjeni. Enye abantu abaningi abayaziyo imithambo evuvukalayo . Lokhu kwenzeka lapho ama-valve emithanjeni engasebenzi kahle, okubangela ukuba igazi lihlangane futhi imithambo ivuvuke, iphenduke, futhi ibonakale ngaphezu kwesikhumba. Lokhu kuvame kakhulu emilenzeni.

Esinye isimo esingaba yingozi kakhulu yi- deep vein thrombosis (DVT) . Lokhu kwenzeka lapho kwakheka ihlule legazi emthanjeni omkhulu ngaphakathi emzimbeni. Uma leli hlule liqhuma futhi lihlala endaweni efana namaphaphu, lingasongela impilo. Abanye abantu bangase babe nemithambo emincane efana nesicabucabu ebonakala ebusweni besikhumba. Nakuba lokhu ngokuvamile kungeyona inkinga enkulu yezempilo, kungaba ukukhathazeka ngezimonyo kwabanye.

Ukuxhumana phakathi kwemithambo yegazi nemithambo yegazi - amabhuloho amancane abizwa ngokuthi ama-capillary

Kulungile, manje sesiyazi ngemithambo yegazi nemithambo yegazi. Kodwa buyini ubudlelwano phakathi kwale 'migwaqo emikhulu' kanye 'nemigwaqo ebuyayo'? Yilapho imithambo yegazi emincane, ethambile ebizwa ngokuthi ama-capillary ingena khona. Lena ifana 'nemigwaqo emincane' ehlukana nemigwaqo emikhulu bese iya ezindlini.

Ama-capillary mancane kakhulu, amanye awo mancane kunezinwele zethu! Kodwa enza umsebenzi obaluleke kakhulu. I-oksijini nezakhamzimba ezivela emithanjeni yegazi kushintshaniswa nawo wonke amaseli emzimbeni, futhi imfucuza kanye ne-carbon dioxide evela emaselini kwenezelwa egazini, ngalezi zinhlayiya. Ngenxa yokuthi lezi zinhlayiya zisakazeka njengenethiwekhi kuwo wonke umzimba wethu, igazi linikezwa kuzo zonke izingxenye ezincane zomzimba. Khona-ke lezi zinhlayiya ziyahlangana ukuze zakhe imithambo yegazi, ethwala igazi elingcolile libuyele enhliziyweni.
