Dambudziko rekuderera kweropa rinoenda kune imwe nzvimbo yeuropi.
Ropa rinotakura oksijeni nemirivo kuburikidza neropa reyeri rinonzi metriyo. Chero hupikano muropa rinoputika muuropi hunosiya huropi hunodiwa oksijeni nemuviri. Izvi zvinokonzera kurashikirwa kwebasa rechikamu cheropi hupi neripi reyeri. Chirwere chinoratidzika seboka rezviratidzo zvinokonzerwa nokurasikirwa kwebasa rechikamu cheuropi.
Chikamu cheuropi chinokonzerwa nehurokwa chinokonzerwa neropa rega rega. Kana chirwere cheropa chichidzivirirwa kana chakavhiringidzika nemhaka yokudonha kana kuparara , izvi zvinoita kuti ropa riwedzerere kana kuti rimire. Mishonga yeropa iyo inopa uropi inopindirana nechikamu cheuropi, kutevera nzira yakanatsanangurwa. Dzimwe nzvimbo dziri muuropi dzingagamuchira ropa kubva kune rimwe ropa rimwe chete, asi kazhinji, imwe yeropa inopa huwandu hweropa mune imwe nzvimbo yeuropi.
Izvi zvinotevera mutsara wemidziyo yeropa iyo, kana yakakuvara, inokonzera chirwere.
Ropa midziyo yeuropi
Carotid arteries - Itirotid arteri dziri pamberi pehuro uye dzinopa huwandu hweropa kuuropi, kunyanya mberi kweuropi. Carotid arteri dziri mumutsipa, saka zvinowanikwa nyore kupfuura mitsipa yeropa muuropi pachake. Izvi zvinobvumira vanachiremba kuti vaongorore hutano hwemakaroti e-carotid vachishandisa midziyo yakafanana neye ultrasound kuti vaone kana mitsetse ye carotid yakamanikana kana ine yakawanda yeholesterol inovaka.
Carotid arteri inowanikwawo zvakanyanya kufanirwa nekugadzirwa kwekupora kupfuura mitsipa yeropa iri mukati meuropi.
Vertebral arteries- Izvozvo zvinonzi arteralal arteries zviri kumashure kwemutsipa uye zvinopa ropa kumashure kweuropi. Izvozvo zvinopa ropa kune chikamu chiduku cheuropi, brainstor , asi chikamu cheropi chinotarisira mabasa anotsigira upenyu sekufema uye kutonga mwoyo.
Basilar artery - The basilar artery ndiyo kubatanidzwa kwema-vertebral arteries kure uye zvakadzika muuropi. Inopa ropa ku brain brain, iyo inodzora kufamba kweziso uye mabasa anotsigira upenyu.
Anterior cerebral artery - Kuruboshwe uye kurudyi anterior cerebral arteries ndiwo matavi echezasi neakarurama carotid arteri, pamwe, uye anopa ropa kumativi ekutanga europi, ayo anotonga maitiro nemafungiro.
Pakati pehutachiita arteri - Pakati peperebral arteries ndiwo mashizha eboshwe uye akarurama carotid arteri, maererano. Iyo midzi inonzi cerebral arteries inopa ropa munzvimbo dzeuropi dzinodzora kufamba. Icho chiri pakati peperesi yecherebrari ariti kurutivi rworuboshwe rweuropi uye imwe kurudyi rwechoro.
Posterior cerebral artery - Inonzi posterior cerebral arteries inobva pamusasa we basilar. Izvo zvakanaka shure kwehutachiona hutachiona hunoisa ropa kumucheto wakatarisa nzvimbo yakarurama yeuropi uye kuruboshwe mushure mekutengesa arteri inopa ropa kumucheto kuruboshwe kuruboshwe rwehuropi.
Kutsika kwemashure ekutaurirana kwepamusoro - Iyo yemaawa ekutumira kukurukurirana inoita kuti ropa riyerere pakati pekurudyi uye kuruboshwe mushure mekupedzisira mashetiriyheni. Izvi zvinopa simba rinodzivirira.
Apo imwe yemashure emakemikari ekupedzisira ekupedzisira inoita shoma shoma, mishonga yokukurukurirana pashure payo inogona kubhadhara kuderedza kuderera nekupa ropa kubva kune rumwe rutivi, segonho kana bhiriji.
Anterior kutaurirana arteri - Anterior kukurukurirana arteri inobatana pakati pekodzero uye kuruboshwe anterior cerebral arteries. Iri ndiro mudziyo, wakafanana neyamapuriti ekukurukurirana, inopa kubatana pakati pezvakarurama uye zvakasara anterior cerebral arteries, iyo inopa chidziviriro chekudzivirira kwekunyorera zvishoma kune rumwe rutivi nokubvumira kugoverwa kweropa kubva kune rumwe rutivi.
Ophthalmic- Ihephthalmic arteries inopa ropa kune ziso uye naizvozvo inopa utano hunokosha hwekuona uye kufamba kweziso.
Retinal - Mishonga ye retinal midziyo miduku yeropa inopa ropa kune chikamu chiduku asi chakakosha cheziso rinonzi retina. Tsvaga zvakawanda pamusoro pekudzoka kwetestro stroke .
Apo imwe nzvimbo yeuropi isingakwanisi kupa ropa, chirwere chinogona kuitika. Zviratidzo zvakabatanidzwa zvinobatsira vanopa utano hwehutano kuti vaone nzvimbo yekurohwa uye iyo yeropa inopinda. Izvi zvinogona kubatsira munguva refu uye kwenguva pfupi kurapwa uye chirongwa chekugadzirisa.
