Blood plasma is the liquid component of blood, in which the blood cells are suspended. Plasma is the largest single component of blood, making up about 55% of total blood volume. Blood plasma contains many vital proteins including fibrinogen, globulins and human serum albumin. Sometimes blood plasma can contain viral impurities which must be extracted through viral processing.
Serum refers to blood plasma in which clotting factors (such as fibrin) have been removed naturally by allowing the blood to clot prior to isolating the liquid component.
Plasma resembles whey in appearance (transparent with a faint straw colour). It is mainly composed of water, blood proteins, and inorganic electrolytes. It serves as transport medium for glucose, lipids, amino acids, hormones, metabolic end products, carbon dioxide and oxygen. The oxygen transport capacity and oxygen content (CaO2) of plasma is much lower than that of the hemoglobin in the red blood cells; the CaO2 will, however, increase under hyperbaric conditions.) Plasma is the storage and transport medium of clotting factors. Its protein content is necessary to maintain the oncotic pressure of the blood, which "holds" the serum within the vessels. The act of separating plasma from red blood cells is called Plasmapheresis.

plasma
Liquid part of blood (including dissolved chemicals but not the cells and platelets). This straw-coloured fluid serves as the blood's transport medium, helps maintain blood pressure, distributes body heat, and maintains the pH balance in the bloodstream and body. More than 90% consists of water, about 7% proteins, and the rest other substances, including waste products of metabolism. Important plasma proteins include albumin, coagulation factors, and globulins, including gamma globulin and a hormone that stimulates erythrocyte formation. Serum is the liquid part of the blood that remains after clotting.

Plasma is a complex substance; its principal component is water. It also contains plasma proteins; inorganic constituents such as sodium, potassium, calcium chloride, carbonate, and bicarbonate; sugar; hormones; enzymes; fats; amino acids; and such waste products as urea and creatinine. All these substances occur in minute quantities.
Among the component plasma proteins are albumin, the principal agent in maintaining the osmotic pressure of the blood and therefore in controlling its tendency to diffuse through the walls of blood vessels; a dozen or more proteins, including fibrinogen and prothrombin, which participate in clotting; agglutinins, which cause the agglutination reaction between samples of blood of different types and the reaction known as anaphylaxis, a form of allergic shock; and globulins of many types, which include the antibodies that provide immunity against many diseases. Other significant plasma proteins function as carriers of such essential tissue nutrients as copper, iron, other metals, and a variety of hormones.
Separation of plasma proteins for individual study was first accomplished in the 1920s; large-scale fractionation, allowing use of the individual fractions, was accomplished during World War II. Some of the results of this work include the use of serum albumin as a substitute for blood or plasma for transfusion; the use of gamma globulin for short-term protection against such diseases as measles and hepatitis; and the use of antihaemophilic globulin for the treatment of haemophilia.
