A unit of donated fresh plasma. Blood plasma is a light amber-colored liquid component of blood in which blood cells are absent, but which contains proteins and other constituents of whole blood in suspension. It makes up about 55% of the body's total blood volume. [1] It is the intravascular part of extracellular fluid (all body fluid outside ...
The most immature blood cell that is considered of plasma cell lineage is the plasmablast. [11] Plasmablasts secrete more antibodies than B cells, but less than plasma cells. [12] They divide rapidly and are still capable of internalizing antigens and presenting them to T cells. [12]

Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), [2] and contains proteins, glucose, mineral ions, and hormones. The blood cells are mainly red blood cells (erythrocytes), white blood cells (leukocytes), and (in mammals) platelets (thrombocytes). [3]
Serum also does not contain all the formed elements of blood, which include blood cells, white blood cells (leukocytes, lymphocytes), red blood cells (erythrocytes), and platelets. [citation needed] The study of serum is serology. Serum is used in numerous diagnostic tests as well as blood typing.
A blood cell (also called a hematopoietic cell, hemocyte, or hematocyte) is a cell produced through hematopoiesis and found mainly in the blood. Major types of blood cells include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
Plasma is then removed from the blood by a cell separator. Three procedures are commonly used to separate the plasma from the blood cells, with each method having its own advantages and disadvantages: [6] Discontinuous flow centrifugation: One venous catheter line is required. Typically, a 300 ml batch of blood is removed at a time and ...
Fresh frozen plasma (FFP) is a blood product made from the liquid portion of whole blood. [3] It is used to treat conditions in which there are low blood clotting factors (INR > 1.5) or low levels of other blood proteins .
