I-Plasma lulwelo olungenaseli olufunyenwe ngokufaka i-centrifuging lonke igazi elishiya umthambo wegazi emva konyango lwe-anticoagulation.Iqukethe i-fibrinogen (i-fibrinogen inokuguqulwa ibe yi-fibrin kwaye ibe ne-coagulation effect).Xa i-calcium ions yongezwa kwi-plasma, i-recoagulation iyenzeka kwi-plasma, ngoko i-plasma ayinayo i-calcium ions yamahhala.
Imisebenzi ephambili yeplasma
1. Umsebenzi wesondlo I-Plasma iqulethe inani elikhulu leprotheyini, edlala umsebenzi wokugcina izondlo.
2. Kukho iisayithi ezininzi zokubopha i-lipophilic ezisasazwa kumphezulu omkhulu wezothutho zeprotheyini, ezinokubophelela kwizinto ezinyibilikayo kwi-lipid, zizenze zinyibilike emanzini kwaye kulula ukuzihambisa.
3. Umsebenzi wokuphazamisa I-albumin yeplasma kunye netyuwa yayo yesodium zenza isibini se-buffer, kunye nezinye iiperi zetyuwa ezingaphiliyo (ingakumbi i-carbonic acid kunye ne-sodium bicarbonate), ukuthintela umlinganiselo we-asidi-base kwi-plasma kunye nokugcina uzinzo lwe-pH yegazi.
4. Ukuqulunqwa koxinzelelo lwe-osmotic ye-colloid Ubukho be-plasma colloid osmotic uxinzelelo yimeko ebalulekileyo yokuqinisekisa ukuba amanzi kwi-plasma akayi kudluliselwa ngaphandle kwemithambo yegazi, ukuze kugcinwe umthamo wegazi ngokuthe rhoqo.
5. Ukuthatha inxaxheba ekusebenzeni komzimba kunye nokudlala indima ebalulekileyo ekufezekiseni umsebenzi wokuzivikela, i-immune antibodies, inkqubo yokuncedisa, njl., yenziwe nge-plasma globulin.
6. Ubuninzi bezinto ze-plasma coagulation, izinto ze-physiological anticoagulant kunye nezinto ezikhuthaza i-fibrinolysis ebandakanyekayo kwi-coagulation kunye nemisebenzi ye-anticoagulation yi-plasma proteins.
7. Imisebenzi yokukhula kwezicubu kunye nokulungiswa kwezicubu ezonakalisiweyo ifezekiswa ngokuguqulwa kwe-albumin kwiiprotheni zezicubu.
