Igazi lijikeleza emzimbeni wonke, linika izondlo kuyo yonke indawo kwaye lisusa inkunkuma, ngoko ke kufuneka ligcinwe phantsi kweemeko eziqhelekileyo. Nangona kunjalo, xa umthambo wegazi wenzakele kwaye waqhekeka, umzimba uya kuvelisa uthotho lweempendulo, kubandakanya i-vasoconstriction ukunciphisa ukulahleka kwegazi, ukuhlanganiswa kweeplatelet ukuvimba inxeba ukuyeka ukopha, kunye nokusebenza kwezinto ezibangela ukuxinana kwegazi ukwenza i-thrombus ezinzileyo ukuthintela ukuphuma kwegazi kunye nenjongo yokulungisa imithambo yegazi yindlela yomzimba yokunciphisa ukuxinana kwegazi.

Ngoko ke, isiphumo somzimba sokuhamba kwegazi sinokwahlulwa sibe ziinxalenye ezintathu. Inxalenye yokuqala iveliswa kukunxibelelana phakathi kwemithambo yegazi kunye neeplatelets, okubizwa ngokuba yi-primary hemostasis; inxalenye yesibini kukusebenza kwezinto ezijikeleza igazi, kunye nokwakheka kwe-reticulated coagulation fibrin, esonga iiplatelets kwaye ibe yi-strombus ezinzileyo, ebizwa ngokuba yi-secondary hemostasis, okuyi-What we caugulation; nangona kunjalo, xa igazi liyeka kwaye lingaphumi, kuvela enye ingxaki emzimbeni, oko kukuthi, imithambo yegazi iyavalwa, eya kuchaphazela ukunikezelwa kwegazi, ngoko ke inxalenye yesithathu ye-hemostasis. Isiphumo sokunyibilika kwe-thrombus kukuba xa imithambo yegazi ifikelela kwisiphumo se-hemostasis kunye nokulungiswa, i-thrombus iya kunyibilika ukubuyisela ukuhamba kakuhle kwemithambo yegazi.

Kuyabonakala ukuba ukujiya kwegazi yinxalenye ye-hemostasis. I-hemostasis yomzimba iyinkimbinkimbi kakhulu. Ingasebenza xa umzimba uyifuna, kwaye xa i-hemostasis yegazi ifezekisile injongo yayo, inokunyibilikisa i-thrombus ngexesha elifanelekileyo kwaye ibuyele esiqhelweni. Imithambo yegazi iyavulwa ukuze umzimba usebenze ngokuqhelekileyo, nto leyo eyinjongo ebalulekileyo ye-hemostasis.

Izifo zokopha ezixhaphakileyo ziwela kwezi ndidi zimbini zilandelayo:

.

1. Ukungasebenzi kakuhle kwemithambo yegazi kunye neeplatelet

Umzekelo: i-vasculitis okanye iiplatelets ezisezantsi, izigulane zihlala zineendawo ezincinci zokopha kwimilenze engezantsi, ezibizwa ngokuba yi-purpura.

.

2. Into engaqhelekanga yokujiya kwegazi

Kuquka i-hemophilia yokuzalwa kunye nesifo sikaWein-Weber okanye i-acquired liver cirrhosis, ityhefu yempuku, njl.njl., kudla ngokubakho amabala amakhulu e-ecchymosis emzimbeni, okanye ukopha kwemisipha enzulu.

Ngoko ke, ukuba unesifo sokopha esingaqhelekanga esichazwe apha ngasentla, kufuneka udibane nogqirha wegazi ngokukhawuleza.
