The liquid portion of the blood, the plasma, is a complex solution containing more than 90 percent water. Plasma is derived when all the blood cells—red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes)—are separated from whole blood. Blood is made up of multiple components, including red blood cells, white blood cells, platelets, and plasma. Plasma fulfills the function of immune protection against possible infections to which the body can be exposed. Blood plasma is actually the dominant component of blood and contains the water, proteins, electrolytes, lipids, and glucose.

They include most of the body’s supply of protective antibodies produced in response to specific viral or bacterial antigens. The liquid portion of blood, plasma comprises 55 percent of blood's total volume, and is itself is composed of 92 percent water. When separated from the rest of the blood, plasma is a light yellow liquid. The resulting liquid, devoid of cells and fibrinogen, is called serum. The other way involves donating only plasma.

For example, one cytokine called erythropoietin, synthesized by specialized kidney cells, stimulates bone marrow blood progenitor cells to produce red blood cells. The cellular elements—referred to as the formed elements—include red blood cells (RBCs), white blood cells (WBCs), and cell fragments called platelets.The extracellular matrix, called plasma, makes blood unique among connective tissues because it is fluid. The fibrinogen content of the blood plasma is 0.2 to 0.4 percent.…. Plasma, also called blood plasma, the liquid portion of blood.
