Luyini uhlelo lwe-venous?

Imithambo uhlobo lwesitsha segazi esibuyisa igazi elingenawo amandla avela ezithweni zakho libuyele enhliziyweni yakho. Lokhu kwehlukile emithanjeni yakho, eletha igazi elinomoya-mpilo lisuka enhliziyweni yakho liye kuwo wonke umzimba wakho.

Igazi elingenawo umoya ogelezela emithanjeni yakho liqoqwa ngaphakathi kwemithambo yegazi emincane ebizwa ngokuthi ama-capillaries. Ama-capillaries yimithambo yegazi emincane kakhulu emzimbeni wakho. Umoya-mpilo udlula phakathi kwezindonga zama-capillaries akho kuya ezicutshini zakho. I-Carbon dioxide nayo ingangena kuma-capillaries akho asuka ezicutshini ngaphambi kokungena emithanjeni yakho.

Uhlelo lwe-venous lubhekisa kwinethiwekhi yemithambo esebenza ukuletha igazi elingena-oxygen enhliziyweni yakho.

Isakhiwo semithambo

Izindonga zemithambo yakho zinezingqimba ezintathu ezihlukene:

• I-Tunica ngaphandle. Lesi yisendlalelo sangaphandle sodonga lwemithambo, futhi futhi siwugqinsi. Iningi lakhiwa izicubu ezixhuma. I-tunica externa iqukethe nemithambo yegazi emincane ebizwa nge-vasa vasorum enikezela ngegazi ezindongeni zemithambo yakho.
• Abezindaba zeTunica. Imidiya ye-tunica ungqimba oluphakathi. Izacile futhi iqukethe inani elikhulu le-collagen. I-Collagen ingenye yezingxenye eziyinhloko zezicubu ezixhuma.
• Tunica intima. Lolu ungqimba lwangaphakathi impela. Ungqimba olulodwa lwamaseli we-endothelium kanye nezinye izicubu ezixhuma. Lolu ungqimba kwesinye isikhathi luqukethe ama-valve wendlela eyodwa, ikakhulukazi emithanjeni yezingalo nemilenze yakho. La ma-valve avimbela igazi ukuba lingageleki emuva.

Izinhlobo zemithambo

Imithambo ivame ukuhlukaniswa ngokuya ngendawo yazo kanye nanoma iziphi izici ezihlukile noma imisebenzi.

Imithambo ye-Pulmonary and systemic

Umzimba wakho uzungeza igazi kumathrekhi amabili ahlukene abizwa nge-systemic circuit kanye ne-pulmonary circuit. Imithambo isuselwa kusekethe ezitholakala ku:

• Imithambo yamaphaphu. Isifunda se-pulmonary sithwala igazi elingenawo amandla avela enhliziyweni yakho liye emaphashini akho. Lapho nje amaphaphu akho efaka umoya oksijini egazini, isifunda se-pulmonary siyibuyisela enhliziyweni yakho. Kunemithambo emine yamaphaphu. Ahlukile ngoba aphethe igazi elinomoya-mpilo. Yonke eminye imithambo ithwala kuphela igazi elingenayo i-oxygen.
• Imithambo ehlelekile. Isekethe ehlelekile ithwala igazi elingenawo amandla emzimbeni wonke emzimbeni libuyele enhliziyweni yakho, lapho lingena khona esifundeni se-pulmonary for oxygen. Imithambo eminingi yimithambo ehlelekile.

Imithambo ejulile nemithambo ekha phezulu

Imithambo yesistimu ibuye ihlukaniswe njenge:

• Imithambo ejulile. Lezi zitholakala emisipheni noma emathanjeni. I-tunica intima yomthambo ojulile imvamisa ine-valve yendlela eyodwa yokuvimbela igazi ukuba lingagxili emuva. Imisipha eseduze nayo icindezela umthambo ojulile ukugcina igazi liqhubekela phambili.
• Imithambo ekha phezulu. Lezi zitholakala kungqimba olunamafutha ngaphansi kwesikhumba sakho. I-tunica intima yomthambo ongaphezulu nayo ingaba ne-valve yendlela eyodwa. Kodwa-ke, ngaphandle kwemisipha eseduze yokucindezela, bavame ukuhambisa igazi kancane kakhulu kunemithambo ejulile.
• Ukuxhuma imithambo. Igazi elivela emithanjeni engaphezulu livame ukuqondiswa emithanjeni ejulile ngemithambo emfushane ebizwa ngemithambo exhumanayo. Amaphayiphu akule mithambo avumela igazi ukuba ligeleze lisuka emithanjeni engaphezulu liye emithanjeni yakho ejulile, kodwa hhayi ngenye indlela.

Umdwebo wesistimu ye-Venous

Sebenzisa lo mdwebo wokusebenzisana we-3-D ukuhlola uhlelo lwe-venous.

Yiziphi izimo ezithinta uhlelo lwe-venous?

Izimo eziningi zingathinta uhlelo lwakho lwe-venous. Ezinye zezinto ezivame kakhulu zifaka:

• I-vein thrombosis ejulile (i-DVT). Kwakheka kwegazi emthanjeni ojulile, imvamisa emlenzeni wakho. Leli hlwili lingahamba liye emaphashini akho, lidale ukubumbana kwamaphaphu.
• I-thrombophlebitis engaphezulu. Umthambo ovuthayo ongaphezulu, imvamisa emlenzeni wakho, uba negazi. Ngenkathi i-clot ngezikhathi ezithile ingahamba iye emthanjeni ojulile, ibangele i-DVT, i-thrombophlebitis ngokuvamile ayibi kakhulu kune-DVT.
• Imithambo ye-Varicose. Imithambo engaphezudlwana engaphezulu kwesikhumba ibonakala ngokuvuvukala. Lokhu kwenzeka lapho ama-valve wendlela eyodwa ediliza noma izindonga ze-vein ziba buthaka, zivumela igazi ukuba lihlehle emuva.
• Ukungasebenzi kahle kwama-venous okungamahlalakhona. Igazi liqoqa emithanjeni engaphezulu futhi ejulile yemilenze yakho ngenxa yokusebenza okungalungile kwama-valve wendlela eyodwa. Ngenkathi ifana nemithambo ye-varicose, ukungasebenzi kahle okungapheli okungapheli kubangela izimpawu eziningi, kufaka phakathi ukuthungwa kwesikhumba okuqinile kanye nezilonda kwezinye izimo.

Ziyini izimpawu zesifo se-venous?

Ngenkathi izimpawu zesimo se-venous zingahluka kakhulu, ezinye ezijwayelekile zifaka:

• ukuvuvukala noma ukuvuvukala
• ubumnene noma ubuhlungu
• imithambo ezizwa ifudumele uma uthintwa
• umuzwa ovuthayo noma wokulunywa

Lezi zimpawu zivame kakhulu emilenzeni yakho. Uma ubona okunye kwalokhu futhi kungathuthuki ngemuva kwezinsuku ezimbalwa, yenza i-aphoyintimenti nodokotela wakho.

Bangakwazi ukwenza i-venography. Kule nqubo, udokotela wakho ujove ngokungafani nokufa emithanjeni yakho ukukhiqiza isithombe se-X-ray sendawo ethile.

Amathiphu emithanjeni enempilo

Landela lawa macebiso ukugcina izindonga namaveluve wakho eqinile futhi esebenza kahle:

• Vivinya umzimba njalo ukugcina igazi lihamba emithanjeni yakho.
• Zama ukugcina isisindo esinempilo, esinciphisa ingozi yokuba nomfutho wegazi ophakeme. Umfutho wegazi ophakeme unganciphisa imithambo yakho isikhathi esengeziwe ngenxa yengcindezi eyengeziwe.
• Gwema ukuma isikhathi eside noma ukuhlala phansi. Zama ukushintsha izikhundla njalo usuku lonke.
• Lapho uhlala phansi, gwema ukweqa imilenze yakho isikhathi eside noma ushintshe njalo izikhundla ukuze umlenze owodwa ungabi ngaphezulu isikhathi eside.
• Lapho undiza, phuza amanzi amaningi bese uzama ukusukuma ulule kaningi ngangokunokwenzeka. Noma uhleli, ungaguqula amaqakala akho ukukhuthaza ukugeleza kwegazi.
