Isifinyezo

Igazi lakho lakhiwe uketshezi nokuqina. Ingxenye ewuketshezi, ebizwa ngokuthi i-plasma, yenziwa ngamanzi, usawoti, namaprotheni. Ingxenye engaphezu kwengxenye yegazi lakho yi-plasma. Ingxenye eqinile yegazi lakho iqukethe amaseli abomvu egazi, amangqamuzana amhlophe egazi nama-platelets.

Amaseli abomvu egazi (i-RBC) aletha umoya-mpilo emaphashini akho uye ezicutshini nasezithweni zakho. Amaseli egazi amhlophe (WBC) alwa nokutheleleka futhi ayingxenye yamasosha akho omzimba. Ama-platelets asiza igazi ukuba lijiye lapho usike noma unenxeba. Umnkantsha wamathambo, into enesiponji ngaphakathi kwamathambo akho, yenza amangqamuzana egazi amasha. Amaseli egazi ayafa njalo futhi umzimba wakho wenza amasha. Amangqamuzana egazi abomvu aphila cishe izinsuku eziyi-120, kanti ama-platelet aphila cishe izinsuku eziyi-6. Amanye amangqamuzana amhlophe egazi aphila isikhathi esingaphansi kosuku, kepha amanye aphila isikhathi eside kakhulu.

Kunezinhlobo ezine zegazi: A, B, AB, noma u-O. Futhi, igazi liba ne-Rh-positive noma i-Rh-negative. Ngakho-ke uma unegazi lohlobo A, kungaba u-A noma u-A negative. Uhlobo oluyilo lubalulekile uma udinga ukumpontshelwa igazi. Futhi i-Rh factor yakho ingabaluleka uma ukhulelwa - ukungahambisani phakathi kohlobo lwakho nolwengane kungadala izinkinga.

Ukuhlolwa kwegazi njengokuhlolwa kwesibalo segazi kusiza odokotela ukuhlola izifo nemibandela ethile. Zisiza futhi nokuhlola ukusebenza kwezitho zakho futhi zibonise ukuthi ukwelashwa kusebenza kahle kangakanani. Izinkinga ngegazi lakho zingafaka ukuphazamiseka kokopha, ukuphazamiseka ngokweqile kanye nokuphazamiseka kweplatelet. Uma ulahlekelwa igazi eliningi, ungadinga ukumpontshelwa.
