Amount of sodium in plasma is
(A) 143 # Blood plasma is a straw colored liquid component of blood that normally holds the blood cells in whole blood in suspension; this makes plasma the extracellular matrix of blood cells.> 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 of 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+, Ca2+, Mg2+, HCO3-, 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.
