Khawuthelekelele ukuba kukho ingxinano enkulu yezithuthi kwindlela enkulu ohlala uhamba ngayo, kwaye indlela ivaliwe ngokupheleleyo. Wenza ntoni ke ngoko? Ixesha elininzi, sibuza umntu oyaziyo kakuhle le ndawo okanye sijonge iimephu zikaGoogle, size sithathe indlela encinci esecaleni ukuze sifike apho siya khona ngaphandle kokubhajwa, akunjalo? Okumangalisayo kukuba, yile nto kanye eyenzekayo ngaphakathi emzimbeni wethu. Ukuba umthambo wegazi omkhulu emzimbeni wethu, oko kukuthi, umthambo wegazi, uvaliwe ngesizathu esithile, umzimba udala inkqubo 'yeendlela ezisecaleni' esiza kuthetha ngayo kweli nqaku namhlanje.
Kalula nje, yintoni i-collateral circulation?
Eli gama lisenokuvakala liyinkimbinkimbi kancinci, kodwa eneneni lilula kakhulu. Ukujikeleza kwegazi emzimbeni yinkqubo apho, xa umthambo omkhulu wegazi (umthambo okanye umthambo) emzimbeni wethu uvalekile okanye wonakele, kwenziwa enye indlela, okanye inkqubo "yokugcina" yemithambo yegazi ukuze ithwale igazi.
Ngamafutshane, le yindlela yendalo yomzimba wethu yokudlula emzimbeni . Njengoko benditshilo ngaphambili, xa indlela ephambili ivaliwe, sikhangela iindlela ezisecaleni, umzimba ukwadala iindlela ezintsha ezisecaleni zokuhamba kwegazi. Le yindlela emangalisayo yokuzikhusela emzimbeni wethu.
Isebenza njani le nkqubo yendalo yokudlula kwindlela ethile?
Ngoku usenokuba ucinga, "Ngoko ke ezi ndlela zisecaleni zenziwe ngequbuliso?" Enyanisweni, oku kunokwenzeka ngeendlela ezimbini.
1. Ukwanda kwemithambo yegazi emincinci ekhoyo: Umzimba wethu unenethiwekhi yemithambo yegazi emincinci kakhulu, engasetyenziswa rhoqo eqhagamshelwe kwimithambo yegazi yethu ephambili. Xa umthambo oyintloko uqala ukuvaleka, umzimba uyayibona le meko. Emva koko, ngokusekelwe kwimiqondiso evela kwingqondo nakwiinkqubo ezahlukeneyo emzimbeni, loo mithambo yegazi mincinci iqala ukwanda kwaye ikhula kancinci kancinci. Emva koko, igazi elalingakwazi ukudlula kumthambo oyintloko liqala ukuhamba kwezi ndlela zintsha zikhuliswe ecaleni.
2. Ukwakheka kwemithambo yegazi emitsha: Ngamanye amaxesha, ingakumbi xa umthambo wegazi omkhulu uvaleka kancinci kancinci, umzimba uqala ukudala imithambo yegazi emitsha. Kwizonyango, le nkqubo siyibiza ngokuba yi-angiogenesis . Umzimba uyaqonda ukuba ubungakanani begazi eliya kwilungu elithile buyancipha. Ngelo xesha, elo lungu ngokwalo likhupha imiqondiso yamachiza, ithi, "Asinagazi laneleyo, yenzani iindlela ezintsha." Ngokufanelekileyo, le mithambo yegazi emitsha iyakhiwa.
Ngokukodwa, uphando lufumanise ukuba ukuzilolonga rhoqo nge-aerobic , njengokubaleka, ukuhamba ngokukhawuleza, kunye nokudada, kukhuthaza ukwakheka kwemithambo yegazi emitsha. Yiyo loo nto ukuzilolonga kulungile entliziyweni.
Ngaba wonke umntu unemithambo yegazi eyongezelelweyo emizimbeni yakhe?
Ewe, sonke sizalwa sinenkqubo ethile yemithambo yegazi edibeneyo. Nangona kunjalo , inani lale mithambo yegazi emzimbeni womntu ngamnye kunye nobukhulu bayo bunokwahluka kumntu nomntu . Kuxhomekeke kwizinto ezininzi, kuquka i-genetics kunye nendlela yokuphila.
Le mithambo yegazi eyongezelelweyo inokuba yeyeentlobo ezintathu eziphambili.
| Uhlobo lwemithambo yegazi | Kalula nje... |
|---|---|
| Imithambo yegazi | Le yimibhobho emikhulu ethwala igazi elineoksijini eninzi ukusuka entliziyweni ukuya emzimbeni wonke. |
| Imithambo yegazi | Le yimibhobho ehambisa igazi elisetyenzisiweyo (igazi elingenaoksijini) lisuka kwiindawo zomzimba libuyela entliziyweni. |
| IiCapillaries | Le yeyona mithambo yegazi mincinci nebuthathaka. Ioksijini kunye nezondlo zitshintshiselwa ukusuka egazini ukuya kwiiseli ngezi. |
Kuphantsi kweziphi iintlobo zezifo apho olu jikelezo lwegazi olubalulekileyo?
Le nkqubo yendalo yokudlula ingasinceda kuyo nayiphi na imeko evala imithambo yegazi. Oku kubaluleke kakhulu kubantu abanezi meko zilandelayo:
- I-atherosclerosis: Oku kukuqina kwemithambo yegazi ngenxa yokuqokelelana kwamafutha kunye ne-cholesterol kwiindonga zemithambo yegazi. Kufana nomhlwa oqokelelana ngaphakathi kombhobho wamanzi. Njengoko umthambo wegazi uvaleka kancinci kancinci, umzimba unexesha lokwenza imithambo yegazi edibeneyo.
- Isifo semithambo yentliziyo: Ukuvaleka kwemithambo yegazi ehambisa igazi entliziyweni. Le yeyona nto ibangela ukuhlaselwa yintliziyo. Nokuba umntu onenkqubo elungileyo yokuxhasa ukuhlaselwa yintliziyo, umonakalo obangelwe yiyo unokuncipha ngandlela ithile.
- I-Ischemic Stroke: I-stroke ebangelwa kukuvaleka komthambo ohambisa igazi engqondweni.
- Isifo semithambo yegazi ejikeleze umzimba (i-PAD): Ukuncitshiswa kwemithambo yegazi ehambisa igazi, ingakumbi emilenzeni. Oku kunokubangela iintlungu emilenzeni xa uhamba.
Kodwa nantsi into ebaluleke kakhulu ekufuneka siyiqonde sonke. Olu jikelezo lwegazi oludibeneyo alulomlingo okanye unyango lwazo zonke izinto . Luyindlela nje yokuzikhusela yomzimba.
Le mithambo yegazi eyongezelelweyo ayinakusoloko ithintela ngokupheleleyo i-ischemia , okanye ukuncipha kokunikezelwa kwegazi kwilungu, okubangelwa zezi meko. Ngamanye amaxesha, ukuba umthambo oyintloko uvalekile ngequbuliso, inkqubo yemithambo yegazi engaphezulu isenokungakwazi ukubonelela ngegazi ngokukhawuleza.
Ngoko ke, ukuba unemeko efana nale, ngokuqinisekileyo kuya kufuneka ubone ugqirha wakho uze ufumane unyango olufanelekileyo , endaweni yokuthembela kuphela kule nkqubo yendalo. Oku kungaba ngumahluko phakathi kobomi nokufa.
Le nkqubo yemithambo yegazi engaphezulu ihlala ixesha elingakanani?
Xa sele kuqalile ukujikeleza kwegazi okuzinzileyo, loo mithambo yegazi eyongezelelweyo inokunceda ukugcina ukuhamba kwegazi okuqhelekileyo emzimbeni kangangeenyanga, kwaneminyaka.
Nangona kunjalo, njengoko sikhula, le mithambo yegazi eyongezelelweyo iyancipha kancinci kancinci, okanye iqale ukuncipha ngobukhulu. Oku sikubiza ngokuba yi-rarefaction . Le meko inokwenzeka ngokukhawuleza kubantu abanesifo sentliziyo. Xa imithambo yegazi eyongezelelweyo incipha ngale ndlela, amandla ayo okunceda ukuba umthambo oyintloko omtsha uvalekile nawo ayancipha. Yiyo loo nto kuthiwa sifanele sinyamekele impilo yethu ngakumbi njengoko sikhula kwaye sinezinye izifo.
Le nkqubo ifumaneka kumalungu eyiphi emzimbeni?
Le nkqubo yokujikeleza kwegazi edibeneyo ifumaneka kwiindawo ezahlukeneyo zomzimba wethu. Le nkqubo yokukhusela inokubonwa naphi na apho kukho umngcipheko wokuvaleka kwemithambo yegazi.
| Ilungu lomzimba | Ukubaluleka |
|---|---|
| Intliziyo | Inceda ekunciphiseni umonakalo entliziyweni ngexesha lokuhlaselwa yintliziyo. |
| Ingqondo | Inceda ngandlela ithile ekuthinteleni ukufa kweeseli zobuchopho xa kwenzeka isifo sohlangothi. |
| Imilenze neenyawo | Inceda ekunciphiseni iintlungu xa uhamba kubantu abanesifo semithambo yegazi ejikeleze umzimba (i-PAD). |
| Izandla | Ukuba imithambo yegazi ehambisa igazi ezandleni iyavaleka, oko kunceda ukugcina ukusebenza kwesandla. |
| Isisu nemiphunga | Le nkqubo ikwasebenza xa kukho ukuvaleka kwemithambo yegazi emikhulu edibanisa la malungu. |
Ngamafutshane, ukujikeleza kwegazi emzimbeni yindlela emangalisayo imizimba yethu enayo yokulwa nomthambo wegazi ovalekileyo. Asiyondlela ingenamsebenzi yokuthintela ngokupheleleyo umonakalo onokubakho ngenxa yokuhlaselwa yintliziyo okanye isifo sohlangothi. Kodwa kwezinye iimeko, inokuba sisixhobo esixabisekileyo nesisindisa ubomi.
Abaphandi bezonyango okwangoku baphanda ukuba kunokwenzeka na ukudala imithambo yegazi eyenziweyo kunye nokufakelwa kwayo kwizigulana. Ukuba iphumelele, olu phando lunokubonelela ngoncedo olukhulu kubantu abaninzi abaphethwe zizifo zemithambo yegazi kwixesha elizayo.
Umyalezo Wokuya Ekhaya
- Ukujikeleza kwegazi nge-collateral yindlela yendalo yomzimba wethu 'yokudlula' okanye 'yokubuyisela' imithambo yegazi.
- Umsebenzi wayo kukubonelela ngeendlela ezahlukeneyo zokuhamba kwegazi xa umthambo omkhulu wegazi uvalekile.
- Ukuzilolonga rhoqo nge-aerobic kukhuthaza uphuhliso lwale nkqubo yendalo yokudlula emzimbeni.
- Nangona le yindlela yokuzikhusela eluncedo kakhulu, khumbula ukuba ayisosisombululo sokugqibela okanye unyango lweemeko ezifana nesifo sentliziyo kunye nestroke.
- Ukuba uneempawu zokuvaleka komthambo wegazi, ezinje ngeentlungu zesifuba, ubunzima bokuphefumla, okanye iintlungu emilenzeni yakho xa uhamba, bona ugqirha wakho ngoko nangoko . Thembela kwiinkqubo zendalo kwaye uphephe ukulibazisa unyango.
