A human blood contains 55% of plasma.
An average person has about 5 liters of blood of which 55 percent is plasma.
Characteristics of Plasma
- Plasma is the liquid portion of the blood. It is 92 percent water.
- Plasma is the straw-colored fluid
- Plasma is the protein salt solution. The protein helps blood to clot, transport substances through the blood, and perform other functions.
- Plasma contains albumin (the primary protein constituent), fibrinogen (responsible for the clotting of blood) and globulins (including antibodies).
- Plasma holds the red blood cells, white blood cells and platelets in the whole blood in suspension. This makes plasma the extracellular matrix of blood cells.
- Plasma contains glucose and other dissolved nutrients.
- Plasma helps in maintaining pH (acid base) balance in the body, which is critical for the cell function.
- It plays a vital role in an intravascular osmotic effect that keeps electrolytes in balanced form and protects the body from infection and other blood disorders.
- Plasma transports materials needed by cells and materials that must be removed from cells, including various ions (Na+, Ca2+, HCO3–, etc), glucose and traces of other sugars, Amino acids, other organic acids, cholesterol and other lipids, hormones, carbon dioxide, urea and other wastes.
- Blood serum is blood plasma without clotting factors; in other words, “pure” blood.
