Plasma yog cov kua cell-dawb tau txais los ntawm centrifuging tag nrho cov ntshav uas tawm hauv cov hlab ntsha tom qab kev kho anticoagulation.Nws muaj fibrinogen (fibrinogen tuaj yeem hloov mus ua fibrin thiab muaj cov nyhuv coagulation).Thaum cov calcium ions ntxiv rau hauv plasma, recoagulation tshwm sim hauv plasma, yog li lub plasma tsis muaj calcium ions dawb.
Lub luag haujlwm tseem ceeb ntawm plasma
1. Khoom noj khoom haus muaj nuj nqi Plasma muaj ntau npaum li cas ntawm cov protein, uas ua si lub luag hauj lwm ntawm cov as-ham cia.
2. Muaj ntau qhov chaw lipophilic binding qhov chaw faib rau ntawm qhov chaw loj ntawm kev thauj cov proteins, uas tuaj yeem khi rau lipid-soluble tshuaj, ua rau lawv cov dej-soluble thiab yooj yim thauj.
3. Buffering muaj nuj nqi Plasma albumin thiab nws cov ntsev ntsev tsim ib khub tsis, ua ke nrog lwm cov inorganic ntsev tsis muaj khub (feem ntau yog carbonic acid thiab sodium bicarbonate), kom tsis txhob acid-base piv hauv plasma thiab tswj cov ntshav pH.
4. Kev tsim ntawm colloid osmotic siab Lub neej ntawm cov ntshav plasma colloid osmotic siab yog ib qho tseem ceeb los xyuas kom meej tias cov dej hauv plasma yuav tsis raug xa mus rau sab nraud ntawm cov hlab ntsha, thiaj li tswj tau cov ntshav ntim tas li.
5. Kev koom tes hauv kev tiv thaiv kab mob hauv lub cev thiab ua lub luag haujlwm tseem ceeb hauv kev ua kom lub cev tiv thaiv kab mob, tiv thaiv kab mob tiv thaiv kab mob, kev ua kom muaj zog ntxiv, thiab lwm yam, muaj cov ntshav plasma globulin.
6. Feem ntau ntawm cov plasma coagulation yam, physiological anticoagulant tshuaj thiab cov khoom uas txhawb fibrinolysis koom nrog hauv coagulation thiab anticoagulation zog yog plasma proteins.
7. Kev ua haujlwm ntawm cov ntaub so ntswg loj hlob thiab kho cov ntaub so ntswg puas tau tiav los ntawm kev hloov pauv ntawm albumin rau hauv cov ntaub so ntswg protein.
