[Answer] The ________ is the fluid component of blood.

Answer: plasma
The ________ is the fluid component of blood.
Serum is the fluid and solute component of blood which does not play a role in clotting. It may be defined as blood plasma without fibrinogens. Serum includes all proteins not used in blood clotting; all electrolytes antibodies antigens hormones; and any exogenous substances (e.g. drugs or microorganisms). Serum does not contain white blood cells (leukocytes) red blood cells (eryth…
Serum is the fluid and solute component of blood which does not play a role in clotting. It may be defined as blood plasma without fibrinogens. Serum includes all proteins not used in blood clotting; all electrolytes antibodies antigens hormones; and any exogenous substances (e.g. drugs or microorganisms). Serum does not contain white blood cells (leukocytes) red blood cells (erythrocytes) platelets or clotting factors. The study of serum is serology. Serum is used in numerous diagnostic tests as well as blood typing. Measuring the concentration of various molecules can be useful for many applications such as determining the therapeutic index of a drug candidate in a clinical trial. To obtain serum a blood sample is allowed to clot (coagulation). The sample is then centrifuged to remove the clot and blood cells and the resulting liquid supernatant is serum .
The serum of convalescent patients successfully recovering (or already recovered) from an infectious disease can be used as a biopharmaceutical in the treatment of other people with that disease because the antibodies generated by the successful recovery are potent fighters of the pathogen . Such convalescent serum ( antiserum ) is a form of immunotherapy .

Such convalescent serum ( antiserum ) is a form of immunotherapy . Serum is also used in protein electrophoresis due to the lack of fibrinogen which can cause false results. Fetal bovine serum (FBS) is rich in growth factors and is frequently added to growth media used for eukaryotic cell culture . A combination of FBS and the cytokine leukemia inhibitory factor was originally used to maintain embryonic stem cells but concerns a…
