Igazi liyajiya ngenxa yokuba igazi lixinene kakhulu kwaye lihamba kancinci, nto leyo ekhokelela ekubeni igazi lijiye.

Kukho izinto ezibangela ukujiya kwegazi. Xa imithambo yegazi iphuma igazi, izinto ezibangela ukujiya kwegazi ziyavuselelwa kwaye zinamathele kwiiplatelets, nto leyo ebangela ukuba i-viscosity yegazi inyuke kwaye ukuhamba kwegazi kunciphe, ngaloo ndlela kuthintele ukuvuza kwegazi kwimithambo yegazi. Ukujiya kwegazi kubaluleke kakhulu kwi-hemostasis eqhelekileyo yomzimba womntu. Ukujiya kwegazi kubhekisa kwinkqubo yokutshintsha kwegazi ukusuka kwimeko yolwelo ukuya kwimeko eqinileyo. Ukujiya kwegazi yindlela yokwandisa uthotho lwezinto ezibangela ukujiya kwegazi. I-Fibrinogen isebenza kwi-fibrin ukwenza i-fibrin clot ukufezekisa injongo ye-hemostasis. Xa umzimba womntu wenzakele, iiplatelets ziyavuselelwa yinxalenye eyonzakeleyo, iiplatelets ziyavuselelwa, kwaye kuvela ama-clots ahlanganisiweyo, adlala indima ephambili ye-hemostatic. Emva koko iiplatelets zenza utshintsho oluntsonkothileyo ukuvelisa i-thrombin, eguqula i-fibrinogen kwi-plasma ekufutshane ibe yi-fibrin. Ama-clots e-Fibrin kunye neeplatelets asebenza ngaxeshanye ukuze abe yi-thrombi, enokuyeka ukopha ngokufanelekileyo.

Xa isigulana senzakele, ukuba igazi alikajiyi, yiya esibhedlele ukuze ufumane unyango ngokukhawuleza.
