It makes up about 55% of the body's total blood volume . It is the intravascular fluid part of extracellular fluid (all body fluid outside cells). It is mostly water (up to 95% by volume), and contains dissolved proteins (6--8%) (i.e.--serum albumins, globulins, and fibrinogen), glucose, clotting factors, electrolytes (Na, Ca, Mg, HCO, Cl, etc .), hormones, carbon dioxide (plasma being the main medium for excretory product transportation) and oxygen . Plasma also serves as the protein reserve of the human body . It plays a vital role in an intravascular osmotic effect that keeps electrolytes in balanced form and protects the body from infection and other blood disorders . </P> <P> Blood plasma is separated from the blood by spinning a tube of fresh blood containing an anticoagulant in a centrifuge until the blood cells fall to the bottom of the tube . The blood plasma is then poured or drawn off . Blood plasma has a density of approximately 1025 kg / m, or 1.025 g / ml . </P>
