Fungidzira muviri wako wese seguta guru, rakabatikana. Ipapo moyo ndiwo tangi guru remvura muguta iroro. Kubva mutangi iri, panofanira kunge paine pombi huru, yakasimba yekutakura mvura kuenda kudzimba dzese nemumigwagwa muguta, handiti? Ndizvo zvakaita tsinga huru yeropa mumuviri wedu, inotakura ropa rakachena, rine oxygen kubva pamoyo kuenda kumuviri wese. Tinodana izvi kuti aorta. Nhasi tichataura nezvechikamu chekutanga uye chakakosha chepombi iyi huru, aorta, yakabatana nemoyo pachawo. Ndiyo aorta inokwira.
Zvichitaurwa zviri nyore, chii chinonzi ascensing aorta?
Zvichitaurwa zviri nyore, ascensive aorta ndiyo chikamu chekutanga cheaorta, tsinga yeropa yakakura kwazvo mumuviri wedu. Kana moyo uchishanda sepombi uye uchipomba ropa, ropa rinotanga rapinda muascensive aorta iyi. Yakaita sechikamu chekutanga chepombi huru inobuda mutangi remvura. Chikamu ichi chinotanga kubva pamoyo choenda kumusoro. Izwi rekuti "aorta" rinoreva "kukwira kumusoro". Saka unogona kuwana pfungwa yenzvimbo yayo kubva pazita iri.
Kubva muchikamu ichi ndipo panoumbwa aorta inodzika uye inobva yafamba ichidzika seaorta inodzika. Kureva kuti, aorta inokwira ndiyo mavambo ehurongwa hukuru hwetsinga dzinopa ropa kumuviri wese.
Izvi zvinobatsira sei miviri yedu?
Basa re ascending aorta rakakosha zvikuru. Fungidzira, mwoyo wedu une makamuri makuru mana. Paaya, ventricle yekuruboshwe ndiyo inopomba ropa rakachena, rine okisijeni kumuviri wese.
Saka, ropa rinopombwa neiyi ventricle yekuruboshwe rinotanga rapinda mu aorta inokwira. Kubva ipapo, nhengo yega yega, sero rega rega, kubva kuuropi kusvika kutsoka, rinowana okisijeni nezvinovaka muviri zvinodiwa kuti rirarame.
Uye pane chimwe chinhu chakakosha. Mwoyo, unopomba ropa mumuviri wese, unodawo ropa kuti rishande, handiti? Mitsipa miviri mikuru yeropa inopa ropa kutsandanyama dzemwoyo, tsinga dzemwoyo, inotangirawo kubva mutsinga iyi inokwira. Saka, zviri pachena kubva pane izvi kuti tsinga inokwira chikamu chakakosha chinopa hupenyu kumoyo pamwe nemuviri wese.
Muchidimbu, aorta inokwira ndiyo inotangira paipi huru inopa ropa kumuviri wedu. Kana paine kakukanganisika kadiki pane izvi, system yese inogona kukanganiswa.
Iri kupi? Rinotaridzika sei?
Aorta inokwira iri mukati mechipfuva chedu, pamusoro chaipo peventricle yekuruboshwe kuruboshwe rwemoyo. Kutaura chokwadi, iri seri kwepfupa rakati sandara riri pakati pechipfuva chedu, sternum.
Pachitarisiko, aorta yese yakaumbwa setsvimbo. Mudzi wetsvimbo iyi, kureva kuti, chikamu chinotangira pamoyo choenda chakananga kumusoro, ndiyo aorta inokwira. Zvadaro pane kukotama mutsvimbo semubato, watinoti aortic arch. Zvadaro chikamu chinodzika sechikamu chirefu chetsvimbo ndiyo aorta inodzika.
Mhepo inokwira yemunhu mukuru ane hutano inowanzo kureba masendimita 5-8 (anenge masendimita 2-3) uye yakafara masendimita 3-4. Inotetepa zvishoma nezvishoma painodzikira.
Zvikamu zve aorta inokwira uye zvikamu zvemadziro ayo
Tsinga iyi inokosha inopatsanurana kuita zvikamu zvidiki. Uye sedzimwe tsinga dzeropa, iyi ine madziro akaumbwa nezvikamu zvakasiyana-siyana. Ngatizvitarisei zvakadzama.

| Aneurysm yeAortic | Ichi ndicho chirwere chinowanzoitika uye chine njodzi. Chinoitika pano ndechekuti nzvimbo isina kusimba mumadziro e aorta inobuda sebharumu. Izvi zvinogona kukonzerwa nezvinhu zvakaita seBP yakakwira, kusvuta, uye majini. Kubuda uku kune njodzi nekuti kunogona kutsemura nepakati pemadziro (Aortic Dissection) kana kuputika zvachose (Rupture) . Kana izvozvo zvikaitika, zvinogona kukonzera kubuda ropa kwakanyanya mumuviri uye kutoisa hupenyu panjodzi. |
| Stenosis yeAortic Valve | Vharuvhu yeaortic yakafanana negonhi. Kana gonhi iri rikasavhurika zvakanaka uye rikava diki, moyo unofanirwa kushanda nesimba kupfuura zvawagara uchiita kuti ropa ribude. Zvakafanana nekuedza kuisa chigaro chikuru negonhi rakamanikana. Nekufamba kwenguva, izvi zvinogona kukonzera kukura kwetsandanyama yemoyo. |
| Kudzoreredza Vharuvhu yeAortic | Chinoitika pano ndechekuti vharuvhu yeaorta haivharike zvachose. Zvinoita sekunge gonhi rakavhurika zvishoma pane kuvharika zvakanaka. Ipapo rimwe ropa rinopombwa rinodzokera mu ventricle yekuruboshwe yemoyo. Izvi zvinoita kuti moyo ufanirwe kupomba ropa rakawanda kupfuura zvaunofanira kuita, uye nekufamba kwenguva, moyo unogona kushaya simba. |
| Vharuvhu yeBicuspid Aortic (BAV) | Kazhinji, vharuvhu yeaortic ine maflaps matatu. Zvisinei, vamwe vanhu vanozvarwa vaine maflaps maviri chete. Dambudziko iri rinogona kukonzera kuti vharuvhu itete nekufamba kwenguva kana kuti ropa ridzokere kumashure. Vanhu vane dambudziko iri vari panjodzi yakakura yekubatwa neaneurysm. |
