Ngatidzidzei nezve 'tsinga huru yeropa' yemwoyo wako (Ascending Aorta) uye kukosha kwayo.

Nhasi tichataura nezvechikamu chakakosha uye, kunyangwe chingaite sechakaoma zvishoma, chiri nyore kunzwisisa chikamu chemuviri wedu. Ndicho (Ascending Aorta) . Zvichitaurwa zviri nyore, ichi ndicho chikamu chekutanga chetsinga huru yeropa, iyo (Aorta) , chinotangira pamoyo wedu uye chinoparadzira ropa kumuviri wese. Zvakafanana nechidimbu chakaiswa mupaipi huru chinounza mvura kubva mutangi remvura kuenda kumba. Saka, ngationei kuti iyi (Ascending Aorta) chii, chii chinoitika kwairi, rudzii rwezvirwere zvingakonzera, uye kuti tingaichengetedza sei ine hutano.

Chii chinonzi (Ascending Aorta)? Chinokonzera chii?

Fungidzira kuti muviri wedu wakaita seguta guru. Imba yega yega, chitoro chega chega, nzvimbo yega yega muguta rino inoda mvura. Saizvozvowo, sero rega rega mumuviri wedu rinoda ropa rakachena, rakazadzwa neokisijeni. Ndiani anopomba ropa iri mumuviri wese? Mwoyo wedu. Ropa rinopombwa nemoyo rinotakurwa mumuviri wese netsinga huru yeropa (Aorta) , kana kuti aorta huru.

Zvino iyi (Aorta) ine zvikamu zvakati wandei.

1. (Kukwira kweAorta): Iyi ndiyo chikamu chinokwira kumusoro painobuda mukamuri guru rinopomba ropa rinonzi Left Ventricle kuruboshwe rwemoyo. Uyu ndiye mutambi wedu mukuru nhasi.

2. (Aortic Arch): Ipapo chubhu iyi inokotama kumusoro semubato wetsvimbo. Inonzi (Aortic Arch).

3. (Aorta Inoburuka): Zvadaro chubhu iyi inodzika, nepachipfuva, nepadumbu. Chikamu ichocho chinonzi (Aorta Inoburuka).

Saka, basa guru re (Ascending Aorta) nderekutora ropa rine oxygen yakawanda rinopombwa nemoyo wotanga kuriendesa ku (Aortic Arch) uye kubva ipapo kuenda kumuviri wese. Kunyanya, tsinga mbiri dzeropa dzinokosha dzinonzi Coronary Arteries dzinopa ropa kumoyo dzinotangira kubva pane iyi (Ascending Aorta). Fungidzira, pombi yemvura inodawo mvura kuti ishande, ndizvo zvinoitwa.

Iyi (Ascending Aorta) iri kupi? Inotaridzika sei?

Iyi (Ascending Aorta) iri muchipfuva chedu, kunyanya pfupa guru riri pakati pechipfuva, kuseri kwe (Sternum) , kuruboshwe rwemoyo. Yakabatana zvakananga ne (Left Ventricle) yemoyo uye inotambanukira kumusoro.

Pachitarisiko, aorta yese inoita kunge tsvimbo diki imwe chete. Aorta inokwira ndiyo chikamu chipfupi chedanda chinotanga pedyo nemoyo choenda kumusoro. Aorta arch ndiyo chikamu chinokotama semubato wedanda.

Ascending Aorta inowanzova pakati pemasendimita mashanu nemasere (anenge masendimita maviri kusvika matatu) uye yakafara masendimita matatu kusvika mana. Inodzikira zvishoma nezvishoma painodzika pasi pechipfuva.

Ndezvipi zvikamu zveAscending Aorta? Inoumbwa sei?

Aorta yese yakakamurwa kuita zvikamu zvikuru zviviri: thoracic aorta uye abdominal aorta.Iyo (Ascending Aorta), (Aortic Arch), uye (Descending Aorta) dzinobatana kuti dziumbe iyo (Thoracic Aorta).

Aorta inokwira inotanga pedyo neAortic Heart Valve, iri kuseri kweLeft Ventricle. Aortic Valve iyi yakaita semusuwo. Inovhurika nekuvharika kuti ropa ribude kubva kuLeft Ventricle richipinda muAorta. Ascending Aorta inogumira pamberi peBrachiocephalic Artery, bazi guru rekutanga rinobuda paAortic Arch.

Ascending Aorta ine zvikamu zviviri zvikuru:

1. (Mudzi weAortic): Uyu ndiwo mudzi we(Ascending Aorta), chikamu chiri pedyo ne(Aortic Valve). Mukati mawo mune mipata midiki yakaita sema bulb inonzi (Aortic Sinuses) . Apa ndipo panotangira kurudyi nekuruboshwe (Coronary Arteries) (tsinga dzinopa ropa kumoyo). Apa ndipo panowanikwawo (Sinotubular Junction - STJ) . STJ ndipo panova ne(Ascending Aorta) tube yakajairika.

2. Tubular (Ascending Aorta): Izvi zvinotanga mushure meSTJ uye zvinoenderera mberi kusvika kuAortic Arch. Hapana imwe tsinga yeropa inobuda kubva muchikamu ichi.

Kufanana nezvimwe zvikamu zveaorta, aorta inokwira inoumbwa nezvikamu zvitatu zvenyama. Funga nezvayo sepombi, ine zvikamu zvitatu:

• (Tunica Intima): Iri ndiro divi remukatikati. Ropa rinoyerera nepakati paro.
• (Media): Iyi ndiyo nhanho yepakati. Ine shinda dzakawanda dzinochinjika. Idzi dzinobvumira (Aorta) kuti ikotame uye itambanuke zvichienderana nekumanikidzwa kweropa. Zvisinei, nekufamba kwenguva, shinda idzi dzinogona kusasimba uye madziro anogona kutetepa.
• (Adventitia): Iri ndiro jira rekunze. Rine mitsipa midiki yeropa inopa chikafu kumadziro eAorta.

Zvichitaurwa zviri nyore, Ascending Aorta i "paipi" inokosha uye yakasimba inotanga yagamuchira ropa kubva pamoyo yotanga kuritumira mumuviri wese.

Ndezvipi zvirwere zvinokanganisa Ascending Aorta?

Zvinosuwisa kuti chikamu ichi chakakosha chinogonawo kukura nezvirwere zvakasiyana-siyana. Ngationei kuti ndezvipi zvikuru:

• Aortic Aneurysms: Iri idambudziko rinowanzoitika. Aneurysm kushaikwa kwemadziro etsinga yeropa, zvichiita kuti ibunduke sebharumu. Anopfuura 50% yeaortic aneurysms muchipfuva anoitika mu ascending aorta. Anogona kuitika mumudzi weaortic kana mu tubular ascending aorta. Aortic aneurysms zvirwere zvinotyisidzira hupenyu. Izvi zvinodaro nekuti aneurysm inogona kukonzera kubvaruka muzvikamu zvetsinga yeropa - chirwere chinonzi aortic dissection . Kana, kana ikatsemuka zvachose, kubuda ropa kwakanyanya kunogona kuitika mumuviri. Izvi zvinokonzeresa emergency.

• (Kuomarara kweAortic Valve Stenosis):Kunyangwe Aortic Valve isiri chikamu cheAscending Aorta, yakabatana nemadziro emukati meAscending Aorta. Aortic Stenosis kutetepa kweAortic Valve pakati peAortic Root neLeft Ventricle. Izvi zvinoita kuti moyo ushande nesimba kupomba ropa muAorta. Izvi zvinogona kukonzera kukura kwetsandanyama dzemwoyo.

• (Aortic Valve Regurgitation): Izvi zvinoitika kana (Aortic Valve) ikasavhara zvakanaka. Zvadaro, pachinzvimbo chekuenda mberi mu (Aorta), ropa rinodzokera mu (Left Ventricle). Izvi zvinoita kuti mwoyo upombe ropa rakawanda kupfuura zvakajairika. Nekufamba kwenguva, moyo unogona kushaya simba. (Aortic Valve Regurgitation) inogonawo kuitika nekuda kwekuti (Ascending Aorta) inokura.

• Bicuspid Aortic Valve (BAV): Vamwe vanhu vanozvarwa vaine tupepa tuviri muaortic valve yavo panzvimbo petutatu. Vanhu vane rudzi urwu rwevharuvhu vari panjodzi yakakura yekuva neaneurysms yeaortic ascending. BAV inogona kukonzera aortic stenosis, aortic regurgitation, kana zvese zviri zviviri.

• Zvirwere zveConnective Tissue: Vanhu vane zvirwere zvakaita se (Marfan Syndrome) , (Loeys-Dietz Syndrome) , uye (Ehlers-Danlos Syndrome) vanogona kuva nematambudziko akaita se (Aneurysms) nekuti madziro e (Aorta) anogona kushaya simba.

• Matambudziko ekuzvimba: Matambudziko akadai seGiant Cell Arteritis uye Penetrating Atherosclerotic Ulcers anogonawo kukuvadza madziro e aorta.

Kunyange zvazvo zviratidzo izvi zvingaita sezvinotyisa, zvinogona kudzorwa kana zvikaonekwa nekukurumidza uye zvikarapwa nemazvo .

Ndingachengetedza sei Ascending Aorta yangu iine hutano?

Zvinhu zvakafanana zvaunoita kuti mwoyo wako nehurongwa hweropa zvirambe zvakanaka zvinobatsirawo pahutano hweAscending Aorta.

• Idya chikafu chine hutano uye chakaringana: Idya chikafu chine munyu mushoma (sodium), cholesterol, uye mafuta akazara. Idya michero yakawanda, miriwo, zviyo zvese, uye fiber.
