Magazi anu amapangidwa ndi madzi ndi zolimba. Gawo lamadzi, lotchedwa plasma, limapangidwa ndi madzi, mchere, ndi mapuloteni. Oposa theka la magazi anu ndi plasma. Gawo lolimba la magazi anu lili ndi maselo ofiira, maselo oyera am'magazi, ndi ma platelet.

Maselo ofiira ofiira (RBC) amatulutsa mpweya m'mapapu anu kupita kumatumba ndi ziwalo zanu. Maselo oyera a magazi (WBC) amalimbana ndi matenda ndipo ndi gawo limodzi lama chitetezo chamthupi anu. Mapaleti amathandiza magazi kuundana mukadulidwa kapena bala. Mafupa a mafupa, omwe amakhala mkati mwa mafupa anu, amapanga maselo atsopano a magazi. Maselo a magazi amafa mosalekeza ndipo thupi lako limapanga zatsopano. Maselo ofiira ofiira amakhala masiku pafupifupi 120, ndipo ma platelet amakhala masiku pafupifupi 6. Maselo ena oyera amakhala ndi tsiku lochepera tsiku, koma ena amakhala ndi moyo wautali kwambiri.

Pali mitundu inayi yamagazi: A, B, AB, kapena O. Komanso, magazi ali ndi Rh-positive kapena Rh-negative. Chifukwa chake ngati muli ndi magazi amtundu wa A, mwina A positive kapena A negative. Mtundu womwe muli ndi wofunikira ngati mukufuna kuthiridwa magazi. Ndipo Rh factor yanu itha kukhala yofunikira ngati mungakhale ndi pakati - kusagwirizana pakati pa mtundu wanu ndi mwana kumatha kubweretsa mavuto.

Kuyezetsa magazi monga kuyezetsa magazi kumathandiza madotolo kuti adziwe ngati ali ndi matenda kapena matenda ena. Amathandizanso kuwunika momwe ziwalo zanu zimagwirira ntchito ndikuwonetsa momwe mankhwala akugwirira ntchito. Mavuto amwazi wanu atha kuphatikizira kusokonekera kwa magazi, kuundana kwambiri ndi ma plateletelet. Mukataya magazi ochulukirapo, mungafunike kuthiridwa magazi.
