Isishwankathelo

Igazi lakho lenziwe lulwelo kunye nokuqina. Inxalenye engamanzi, ebizwa ngokuba yiplasma, yenziwe ngamanzi, iityuwa, neeproteni. Ngaphezu kwesiqingatha segazi lakho yiplasma. Icandelo eliqinileyo legazi lakho lineeseli ezibomvu zegazi, iiseli ezimhlophe zegazi kunye neeplatelets.

Iiseli ezibomvu zegazi (i-RBC) ihambisa ioksijini kwimiphunga yakho iye kwizicwili nakwizitho zakho. Iiseli ezimhlophe zegazi (i-WBC) zilwa nosulelo kwaye ziyinxalenye yamajoni akho omzimba. Iiplatelets zinceda igazi ukuba lijiye xa usikekile okanye unenxeba. Umongo wethambo, into exineneyo ngaphakathi kwamathambo akho, yenza iiseli ezintsha zegazi. Iiseli zegazi ziyafa rhoqo kwaye umzimba wakho wenze ezintsha. Iiseli ezibomvu zegazi zihlala malunga neentsuku ezili-120, kwaye iiplatelets zihlala malunga neentsuku ezi-6. Ezinye iiseli ezimhlophe zegazi zihlala ngaphantsi komhla, kodwa ezinye ziphila ixesha elide kakhulu.

Kukho iintlobo ezine zegazi: A, B, AB, okanye O. Kwakhona, igazi linokuba ne-Rh-positive okanye i-Rh-negative. Ke ukuba unoluhlobo lwegazi A, nokuba ngu-A okanye u-A negative. Loluphi uhlobo olulo olubalulekileyo ukuba ufuna utofelo-gazi. Kwaye i-Rh factor yakho inokubaluleka ukuba ukhulelwe-ukungahambelani phakathi kohlobo lwakho kunye nolomntwana kunokudala iingxaki.

Uvavanyo lwegazi olufana nokuvavanywa kokubalwa kwegazi kunceda oogqirha ukujonga izifo kunye neemeko ezithile. Ziyanceda ukujonga ukusebenza kwamalungu akho kwaye zibonise indlela ezisebenza ngayo unyango. Iingxaki ngegazi lakho zinokubandakanya ukuphazamiseka kwegazi, ukudinwa okugqithisileyo kunye nokuphazamiseka kweplatelet. Ukuba uphulukana negazi elininzi, kusenokufuneka utofelwe igazi.
