Imwa amuna achikulire pafupifupi 5 malita (4.75 malita) a magazi, opangidwa ndi pafupifupi 3 malita (2.85 malita) a plasma ndi 2 malita (1.9 malita) a maselo.
Maselo a magazi amaimitsidwa mu plasma, yomwe ili ndi madzi ndi zinthu zosungunuka, kuphatikizapo mahomoni, ma antibodies, ndi ma enzyme omwe amatengedwa kupita ku minyewa, ndi zinyalala zama cell zomwe zimatengedwa kupita ku mapapo ndi impso.
Maselo akuluakulu a magazi amagawidwa kukhala maselo ofiira (erythrocytes), maselo oyera (leukocytes), ndi mapulateleti (thrombocytes).
Maselo ofiira ndi ofooka, ozungulira, ozungulira, okhala ndi hemoglobin, mankhwala ovuta kwambiri omwe amanyamula mpweya ndi carbon dioxide.
Hemolysis imachitika pamene nembanemba yopyapyala yoteteza yomwe imatsekereza maselo ofiira osalimba imasweka, zomwe zimapangitsa kuti hemoglobin itulukire m'madzi a m'magazi.Hemolysis imatha chifukwa chogwira movutikira magazi, kusiya ulendowo kwa nthawi yayitali (kuyambitsa kusakhazikika kwa magazi) kapena kufinya chala chala kwambiri panthawi yosonkhanitsa capillary, dilution, kukhudzana ndi zonyansa, kutentha kwambiri, kapena matenda.
Cholinga chachikulu cha maselo oyera ndi kulimbana ndi matenda.Mwa munthu wathanzi, maselo oyera amayankha ku matenda ang'onoang'ono poonjezera chiwerengero ndikuchotsa tizilombo toyambitsa matenda.Mapulateleti ndi tiziduswa tating'ono ta maselo apadera omwe amathandiza kuti magazi aziundana.
Ma plasma kapena seramu amatha kulekanitsidwa ndi maselo amwazi mwa centrifugation.Kusiyana kofunikira pakati pa plasma ndi seramu ndikuti plasma imasunga fibrinogen (gawo lotsekera), lomwe limachotsedwa mu seramu.
Seramu imachokera ku magazi oundana omwe sanasakanizidwe ndi anticoagulant (mankhwala omwe amalepheretsa kutsekeka kwa magazi).Magazi oundanawa ndiye kuti amakhala centrifuged, kutulutsa seramu, yomwe ili ndi mitundu iwiri ya mapuloteni: albumin ndi globulin.Seramu nthawi zambiri imasonkhanitsidwa mumachubu ofiira / imvi, golide, kapena chitumbuwa, ndipo machubu ofiira amagwiritsidwa ntchito nthawi zina.
Plasma imachokera ku magazi omwe asakanizidwa ndi anticoagulant mu chubu chotolera ndipo, motero, sanatseke.Mwazi wosakanizika umenewu ungakhale centrifuged, wotulutsa madzi a m’magazi, amene ali ndi albumin, globulin, ndi fibrinogen.
Pali zinthu zambiri za coagulation (factor VIII, factor IX, etc) zomwe zimakhudzana ndi kutsekeka kwa magazi.Mitundu ingapo ya anticoagulants imasokoneza magwiridwe antchito azinthu izi kuti aletse kutsekeka.Ma anticoagulants ndi ma preservatives angafunike pazitsanzo za plasma.Anticoagulant yotchulidwa kapena preservative iyenera kugwiritsidwa ntchito pakuyesa kolamulidwa.Mankhwalawa asankhidwa kuti asunge mbali ina ya chitsanzocho ndikugwira ntchito ndi njira yomwe imagwiritsidwa ntchito poyesa.Magazi otengedwa ndi anticoagulant amodzi oyenera kuyezetsa komwe akufotokozedwa sangaganizidwe kuti ndi oyenera kuyezetsa kwina.Chifukwa zowonjezera sizingasinthidwe, ndikofunikira kuyang'ana gawo lofunikira la mafotokozedwe a mayeso kuti mudziwe zofunikira zosonkhanitsira pamayeso omwe adalamulidwa.
