Igazi liyajiya ngenxa yokujiya kwegazi okuphezulu kanye nokugeleza kwegazi okuhamba kancane, okuholela ekujiya kwegazi.

Kukhona izinto ezibangela ukujiya kwegazi. Lapho imithambo yegazi iphuma igazi, izinto ezibangela ukujiya kwegazi ziyavuselelwa futhi zinamathele kuma-platelet, okwenza ukuba ukujiya kwegazi kwande futhi ukugeleza kwegazi kwehle, ngaleyo ndlela kuvimbele ukuvuza emithanjeni yegazi. Ukujiya kwegazi kubaluleke kakhulu ekujiya kwegazi okuvamile emzimbeni womuntu. Ukujiya kwegazi kubhekisela enkambisweni yokushintsha kwegazi kusuka esimweni soketshezi kuya esimweni esiqinile. Ukujiya kwegazi kuyindlela yokukhulisa uchungechunge lwezinto ezibangela ukujiya kwegazi. I-Fibrinogen ivuselelwa ibe yi-fibrin ukuze yakhe i-fibrin clot ukuze kufezwe injongo ye-hemostasis. Lapho umzimba womuntu ulimele, ama-platelet akhuthazwa yingxenye elimele, ama-platelet ayavuselelwa, bese kuvela ama-clot ahlanganisiwe, okudlala indima eyinhloko ye-hemostatic. Ngemuva kwalokho ama-platelet enza izinguquko eziyinkimbinkimbi ukuze akhiqize i-thrombin, eguqula i-fibrinogen ese-plasma eseduze ibe yi-fibrin. Ama-clot e-Fibrin nama-platelet asebenza ngesikhathi esisodwa ukuze abe i-thrombi, engamisa ukopha ngempumelelo.

Uma isiguli silimele, uma igazi lingajiyi, hamba uye esibhedlela ukuze uthole ukwelashwa ngokushesha.
