Igazi lijikeleza kuwo wonke umzimba, libonelela ngezondlo kuyo yonke indawo kwaye lithatha inkunkuma, ngoko kufuneka ligcinwe phantsi kweemeko eziqhelekileyo.Nangona kunjalo, xa umthambo wegazi wonzakele kwaye ugqabhukile, umzimba uya kuvelisa uthotho lweempendulo, kubandakanya i-vasoconstriction ukunciphisa ukulahleka kwegazi, ukuhlanganiswa kweplatelet ukuvala isilonda ukuba siyeke ukopha, kunye nokusebenza kwezinto ezidibanisayo ukwenza i-thrombus ezinzile ngakumbi ukuvala. ukuphuma kwegazi kunye Injongo yokulungisa imithambo yegazi yindlela yomzimba yokopha.

Ngoko ke, umphumo we-hemostatic womzimba unokwahlulwa ube ngamacandelo amathathu.Inxalenye yokuqala iveliswa yintsebenziswano phakathi kwemithambo yegazi kunye neeplatelet, ezibizwa ngokuba yiprimary hemostasis;inxalenye yesibini kukusebenza imiba coagulation, kunye nokwakheka reticulated coagulation fibrin, leyo isonga iiplatelet kwaye ibe thrombus ezinzile, leyo ibizwa ngokuba hemostasis yesibini, nto leyo esiyibiza ngokuba coagulation;nangona kunjalo, xa igazi liyeka kwaye lingaphumi, enye ingxaki ivela emzimbeni, oko kukuthi, imithwalo yegazi ivaliwe, eya kuchaphazela ukunikezelwa kwegazi, ngoko ke inxalenye yesithathu ye-hemostasis yi-Isiphumo sokuchithwa kwe-thrombus kukuba. xa umthambo wegazi ufezekisa umphumo we-hemostasis kunye nokulungiswa, i-thrombus iya kuchithwa ukuze ibuyisele ukuhamba kakuhle komthambo wegazi.

Ingabonwa ukuba i-coagulation ngokwenene yinxalenye ye-hemostasis.I-hemostasis yomzimba inzima kakhulu.Inokuthi isebenze xa umzimba uyifuna, kwaye xa i-coagulation yegazi iphumelele injongo yayo, inokunyibilikisa i-thrombus ngexesha elifanelekileyo kwaye iphinde ibuyele.Imithambo yegazi ayivalwanga ukuze umzimba usebenze ngokuqhelekileyo, eyona njongo ibalulekileyo ye-hemostasis.

Ezona zifo zixhaphakileyo zokopha ziwela kwezi ndidi zimbini zilandelayo:

.

1. Ukungahambi kakuhle kwemithambo kunye neplatelet

Umzekelo: i-vasculitis okanye iiplatelet eziphantsi, izigulane zihlala zineendawo ezincinci zokopha kwiindawo ezisezantsi, eziyi-purpura.

.

2. Into engaqhelekanga ye-coagulation

Kubandakanya i-congenital hemophilia kunye nesifo sika-Wein-Weber okanye ukufumana i-cirrhosis yesibindi, ityhefu yeempuku, njl.

Ngoko ke, ukuba unokopha okungaqhelekanga, kufuneka udibane ne-hematologist ngokukhawuleza.
