Yenzeka of valve inhliziyo

Nenhliziyo isimiso sokujikeleza kwegazi iyinkimbinkimbi kakhulu. Ngenxa yalokho, kukhona izifo eziningi, ngokuvamile esinzulu noma ngisho okuyisimo esisongela ukuphila. Enye yezimbangela ezivame kakhulu ukufa emhlabeni yokubulawa isifo senhliziyo.

Inhliziyo isitho eziyize kwemisipha ise ohlangothini lwesobunxele thorax. Inhliziyo iyingxenye eyinhloko isimiso sokujikeleza kwegazi. Kusebenza njengomnyombo futha igazi elibangela lesi sifo igazi ukuhambisa wonke umzimba.

ukwahlukanisa inhliziyo ihlukaniswe yaba izingxenye ezimbili: kwesokunxele bese kwesokudla. Ngakwelinye ihlangothi, ohlangothini ngalinye ihlukaniswe ngezigodi i engxenyeni engenhla noma ATRIUM kanye engxenyeni engezansi, noma i-ventricle. Ngakho, lesi simiso yinhliziyo yomuntu has izimbotshana ezine:

• i-ATRIUM kwesokudla,
• i-ventricle yangakwesokudla,
• i-ATRIUM kwesokunxele,
• i-ventricle engakwesobunxele.

Inhliziyo valve ukuxhuma lezi izimbotshana nomphumela yabo ixhomeke umehluko ingcindezi nhlangothi zombili valve. Senhliziyo umjikelezo ingcindezi ukwahlukahlukana izimbotshana kwenhliziyo, esivusa lesilinganiselwa valve - ukuvulwa kanye lokuvala.

valve Atrioventricular, noma enezinto looped, ehlukanisiwe ingaphakathi atrial ventricular izimbotshana.

Zonk valve kwakwakhe kuyinto i-ventricle engakwesobunxele ukuba le-aorta ne-ventricle yangakwesokudla sesihlahla yamaphaphu.

Amaphayiphu wenza umsebenzi sawo inqobo zingenakubekwa zamehlo.

Ukuphazamiseka kwekhono valve kungenzeka kungenxa azalwa naso, noma amukele imbangela isifo, ngokuvamile ezibangelwa rheumatism.

Zimbili izinhlobo izifo valve: umphini esingamahlalakhona futhi izimbobo Umkhawulo noma stenosis.

Lapho ukwehluleka of valve, valve akuzona kahle avaliwe futhi emuva ingxenye igazi agelezela, isibonelo, i-ATRIUM noma ventricle kusukela aorta ukuba i-ventricle engakwesobunxele emuva. Ngenxa yalokho, ngo-izimbotshana we inhliziyo aqoqana igazi kakhulu, futhi umzimba ongawamukeli kuyo lemali edingekayo.

Stenosis wegazi ugobhozela yezinto ezinzima izimbobo.

I valve wenhliziyo kumele kube ngokunembile kakhulu ukwenza umsebenzi walo - ngesikhathi esifanele ukuba uvale futhi evulekile. Lesi sifo kwenzeka uma valve ayisekho enze lo msebenzi. Izifo kubangele ubunzima kwegazi. Ngezinye izikhathi kuba ukuvuvukala valve inhliziyo, lapho enezinto ensikeni ukuzalela amagciwane ukusebenza evamile zenhliziyo. Lesi sifo okuthiwa endocarditis virus. Izifo valve inhliziyo avame aphathwe surgically - ngokususa ukukhubazeka esebenzisa msebenzi.

Ngokuvamile esetshenziswa ukuhlinzwa ukuze esikhundleni noma buyisela valve. Endabeni ka esikhundleni valve kukhona izimila ezisetshenziswa, izimila zokwenziwa noma izilwane.

Uma ngaphambili zokwakha of valve inhliziyo zenziwa kuphela surgically ukuvula esifubeni yokuxhuma isiguli umshini heart-lung, kodwa manje ososayensi iye yasiza ukugxilisa valve inhliziyo ngendlela kancane koda, ngokwenza imbobo encane esifubeni ngakwesobunxele. Valve yenzeka wenziwa ngokusebenzisa ingxenye yokugcina inhliziyo usebenzisa ipayipi akhethekile nge ibhola ekhethekile, valve entsha sifakwe esikhundleni esidala.

Lolu hlobo lokuhlinzwa has inzuzo iziguli emaqenjini ephezulu kuhlinzwa linobungozi ezifana ezigulini esezikhulile nezifo concomitant ezahlukene, noma iziguli ezine ingozi eliphezulu ngokusungula indlela yokubulala izinzwa. Ongoti odokotela abahlinzayo inhliziyo uzizwa ukuthi ukuhlinzwa ukuze esikhundleni valve inhliziyo uzoqhubeka kwenziwe kokubili izindlela, ngoba esimweni ngasinye sihlukile. Esikhathini odokotela abahlinzayo eduze esizayo uhlela ukwenza esinye isinyathelo phambili futhi ezifakelwa inhliziyo valve ngokusebenzisa Umthambo umlenze.

Bheka mayelana nesimo se inhliziyo yakho bese anqume uhlobo oluhle ukwelashwa, uma kunesidingo, in the best of the imitholampilo engcono. ukuphathwa Ikhwalithi izifo zenhliziyo ingatholakala izikhungo inhliziyo eJalimane. Leli zwe ikufakazele ngokuphindaphindiwe idumela lalo njengoba omunye the best in izindlela zanamuhla zokwelapha.
