Uyazi ukuba sinenethiwekhi yemithambo yegazi esasazeke emizimbeni yethu. Ezi zifana neendlela ezihamba kulo lonke ilizwe. Ezinye zifana neendlela ezinkulu, ezinye zifana neendlela ezincinci ezisecaleni. Kodwa kule nkqubo yemithambo, uninzi lwabantu lunemithambo enye kuphela, ekhethekileyo kancinci, kwaye ibaluleke kakhulu. Namhlanje sithetha ngalo mthambo uninzi lwabantu abangazange bawuve ubizwa ngokuba yi-Azygos vein.
Ngamafutshane, yintoni i-Azygos Vein?
Khawucinge ukuba lo ngumthambo omkhulu ohamba kwicala lasekunene lesifuba sakho, kufutshane kakhulu nomqolo wakho. Ngokuchanekileyo, ungaphakathi kwesifuba sakho (isifuba). Lo mthambo udlala indima ebaluleke kakhulu kwinkqubo yokujikeleza kwegazi emzimbeni wethu.
Umsebenzi wayo oyintloko kukuqokelela igazi "elingcolileyo" eliphuma kwisifuba sakho nasesiswini uze ulithwale uliyise entliziyweni. Ngaphambi kokuba liye entliziyweni, eli gazi liqokelelwa kwi-vena cava ephezulu, enye yezona veins zinkulu emzimbeni wethu. Ukusuka apho, igazi liya kwi-atrium yasekunene yentliziyo. Emva kokuba liye entliziyweni, igazi lizaliswa yi-oxygen kwakhona, "licocwe" kwaye liqala ukujikeleza emzimbeni wonke.
Inkqubo yemithambo ye-azygos yimbali enkulu!
Lo mthambo we-Azygos awungomthambo mnye. Ufana nentloko yenkqubo yonke `(inkqubo yemithambo yegazi ye-azygous)`. Kukho eminye imithambo emincinci emininzi kule nkqubo. Eyona nto ibalulekileyo ngale nkqubo kukuba isebenza njengonxibelelwano olongezelelweyo , okanye indlela 'yokudlula', phakathi kwemithambo emibini emikhulu emzimbeni wethu, `i-vena cava engaphantsi' (umthambo oyintloko othwala igazi ukusuka kwicala elingezantsi) kunye ne-`vena cava ephezulu' (umthambo oyintloko othwala igazi ukusuka kwicala eliphezulu).
Khawucinge ukuba zombini iindlela eziphambili eziya eColombo zivalwe ziimoto. Bekuya kuba luncedo kangakanani ukuba bekukho enye indlela yokudlula ukuze izithuthi ziyisebenzise? Yile ndlela le nkqubo injalo. Ukuba omnye wemithambo emibini ephambili uvalekile okanye uvalekile ngandlela thile, igazi lingahamba liye entliziyweni ngale nkqubo ye-Azygos. Kwizonyango, oku sikubiza ngokuba yi-"anastomosis".
Makhe sijonge amanye amalungu amabini aphambili ale nkqubo.
| Igama lomthambo | Ingcaciso elula |
|---|---|
| Umthambo we-hemiazygos oncedisayo | Iqala kwiindawo eziphakathi kweembambo zakho, inyuke iye kwicala lasekhohlo lomqolo wakho, ize ekugqibeleni ithululele kwimithambo ye-azygos. |
| Umthambo weHemiazygos | Oku kwenziwa kukudibana kweminye imithambo emincinci emininzi, njengemithambo esemgogodleni kunye nemithambo engaphantsi kweembambo. Lo mthambo ekugqibeleni uqokelela igazi kwimithambo ye-Azygos. |
Ngamafutshane, le mithambo mibini mincinci ifana nemilambo emibini emincinci. Yomibini le milambo iyahamba ize idibane ibe ngumlambo omkhulu obizwa ngokuba yi-Azygos. Emva koko loo mlambo mkhulu uyahamba uze udibane ube lulwandle olukhulu olubizwa ngokuba yi-'superior vena cava'.
Lo mthambo wahluke njani kweminye imithambo?
Nantsi into ekhethekileyo. Ngokwesiqhelo, imithambo emzimbeni wethu ihlelwe ngababini . Oko kuthetha ukuba ukuba kukho umthambo kwicala lasekunene, kukho nomnye ngasekhohlo. Kodwa indlela umthambo we-azygos obekwe ngayo yahlukile kancinci. Uninzi lwabantu lunomthambo we-azygos omnye kuphela kwicala lasekunene. Uyedwa. Kodwa kunqabile kakhulu, abanye abantu banokuvelisa imithambo emibini ye-azygos ngelixa bekhula esibelekweni sikamama. Yimeko eqhelekileyo leyo.
Ngoko ke inkulu kangakanani le nto?
Le vein idla ngokuba malunga ne-1 centimeter ububanzi. Ngamafutshane, ilingana nebhetri ye-AAA esiyisebenzisa kwiitotshi nakwii-remote controls.
Yenziwe ngantoni le mthambo?
Njengeminye imithambo yegazi, le ifana nombhobho oguquguqukayo onodonga olwenziwe ngamaleya amathathu.
- Umaleko ongaphakathi: Lo wenziwe luhlobo lweseli olubizwa ngokuba zii-endothelial cells. Ezi zivelisa iikhemikhali ezinceda imithambo yegazi ukuba ifinyele kwaye ikhule.
- Umaleko ophakathi: Oku kwenziwe ngezihlunu ezithambileyo. Oku kuvumela umthambo ukuba uthambe kakhulu.
- Umaleko ongaphandle: Lo wenziwe zizicubu ezidityanisiweyo ezibizwa ngokuba yi-`(collagen)` kunye ne-`(elastin).` Oku kunika umthambo amandla kunye nokuthamba.
Ziziphi iingxaki kunye neemeko ezichaphazela umthambo we-azygos?
Ngokwesiqhelo, asifane sibe neengxaki ngalo mthambo kubomi bethu bemihla ngemihla. Nangona kunjalo, kukho iimeko apho unokonakala okanye umsebenzi wawo unokutshintsha.
1. Ukwanda okanye ukudumba komthambo: Ukuba ukuhamba kwegazi kuthintelwe ngenxa yokunyuka koxinzelelo lwegazi okanye ukuvaleka komthambo, umthambo we-azygos unokwanda okanye uvuvuke.
2. Ukwenzakala: Kwiingozi ezinkulu, ingakumbiLo mthambo ungaqhekeka okanye uqhekeke kwiimeko ezifana neengozi zeemoto, ukuwa ukusuka phezulu, okanye ukubetheka kakhulu esifubeni ngelixa udlala imidlalo. Le yimeko eyingozi kakhulu.
3. Umonakalo ngexesha lotyando: Ezinye iindlela zotyando lwesifuba zingonakalisa lo mthambo. Kwakhona, iingxaki ezivela kwizixhobo ezifana nee-pacemakers ezifakwe entliziyweni zinokuchaphazela lo mthambo.
Kwiimeko ezinjalo, uxinzelelo lwegazi kwimithambo lunokunyuka okanye lunciphe kakhulu.
Uvavanyo lokufumanisa ukuba kukho ingxaki na
Ukuba ugqirha wakho urhanela ukuba kukho ingxaki ngale mthambo, unokucebisa iimvavanyo ezahlukeneyo ukuze ayiqinisekise.
| Igama lovavanyo | Kwenzekani? |
|---|---|
| I-Arteriogram okanye iVenogram | Kufakwa idayi ekhethekileyo emithanjeni kwaye kuthathwa uthotho lwemifanekiso ye-X-ray. Oku kuvumela igazi ukuba lihambe kakuhle. |
| I-X-reyi yesifuba | Oku kungakunika umbono ocacileyo ukuba kukho umahluko omkhulu kwimilo okanye ubungakanani bomthambo. |
| Iskeni ye-CT | Oku kuvumela imifanekiso eneenkcukacha ezingaphezulu, enemilinganiselo emithathu yezitho zomzimba kunye nemithambo engaphakathi esifubeni. |
| Iskeni ye-MRI (i-MRI) | Oku kuvumela imifanekiso ecacileyo yezicubu ezithambileyo zomzimba kunye nemithambo. |
Uyiphatha njani umonakalo?
Ukuba lo mthambo wonakele ngenxa yengozi okanye esinye isizathu kwaye uqala ukopha, oogqirha baya kuthatha amanyathelo ngoko nangoko. Kusenokufuneka bavule isifuba baze benze inkqubo yotyando (thoracotomy) ukuze banciphise uxinzelelo esifubeni kwaye basuse igazi eliqokelelweyo.
Abanye abantu bazalwa beneziphene ezithile zokuzalwa kule ndlela. Abantu abanjalo banokuba semngciphekweni wokufumana izifo ezinxulumene ne-spleen okanye isifo sentliziyo sokuzalwa. Nangona kunjalo, ezi azixhaphakanga kakhulu.
Yintoni onokuyenza ukuze ugcine inkqubo yakho yemithambo-luvo isempilweni?
Le mikhwa iya kukunceda kakhulu ukugcina kungekuphela nje umthambo we-azygos, kodwa nayo yonke inkqubo yakho yokujikeleza kwegazi isempilweni.
- Yitya ukutya okunesondlo. Nciphisa ukutya okuneoyile eninzi, ityuwa, kunye neswekile kangangoko unako.
- Zilolonge rhoqo. Nokuba yinto elula njengokuhamba imizuzu engama-30 ngosuku yanele.
- Sela amanzi aneleyo. Kubaluleke kakhulu ukusela ubuncinane iilitha ezi-2-3 zamanzi ngosuku.
- Ukuba une-high blood pressure, yilawule kakuhle. Thatha amayeza owanikwe ngugqirha wakho ngexesha.
- Ukuba uyatshaya, yeka namhlanje. Ukutshaya ngowona monakalo mkhulu onokuyenza kwimithambo yakho yegazi.
Umthambo we-azygos liqhawe elithuleyo kodwa elibaluleke kakhulu emzimbeni wethu. Ukuba unemibuzo engaphezulu ngayo, okanye ukuba uneenkxalabo malunga nempilo yakho, umntu ofanelekileyo ukuthetha naye ngugqirha wosapho lwakho.
Umyalezo Wokuya Ekhaya
- Umthambo we-azygos ngumthambo omkhulu ohamba kwicala lasekunene lesifuba sakho, kufutshane nomqolo wakho.
- Umsebenzi wayo oyintloko kukuthwala igazi elingena-oxygen ukusuka ngasemva kwesifuba nesisu ukuya entliziyweni.
- Ukuba umthambo oyintloko uvalekile, le nkqubo yemithambo isebenza njengendlela eyongezelelweyo (yokudlula) ukuze igazi lihambe.
- Lo mthambo ungonakaliswa kwiingozi ezinkulu, ngoko ke kubalulekile ukufuna ingcebiso kagqirha xa kukho nakuphi na ukubetheka okukhulu esifubeni.
- Ukulandela indlela yokuphila esempilweni yeyona ndlela ilungileyo yokugcina yonke imithambo yakho isempilweni.
