Plasma

= Blood plasma = Blood plasma is a yellowish, weakly basic solution of proteins, electrolytes and small organic molecules. Its volume corresponds to 5%   body weight. They make up approximately 55%  of the blood volume and 25% of the extracellular fluid volume. It is not only enclosed in the extracellular fluid, but it is exchanged with intracellular fluid - 70%  blood plasma is exchanged in one minute.
