Blood Plasma Composition, Function, and Blood Type Compatibility in Transfusion Medicine
Overview
This paper examines the composition and physiological roles of blood plasma as the liquid component of blood, detailing its constituent elements including proteins, electrolytes, and dissolved nutrients. It further analyzes blood group compatibility systems, specifically the ABO blood typing classification and transfusion compatibility protocols to prevent adverse hemolytic reactions.
What this coursework covers

The Blood Plasma- (Q2)
The plasma is the most considerable component and liquid portion of the blood. It appears straw-colored or light-yellowish and is extracted when all the cells (leukocytes, RBCs, and platelets) are removed. More than 90 percent of this component is water, while the rest consists of dissolved substances. These include hormones, antibodies, proteins, electrolytes, nutrient molecules, and gases. Blood plasma acts as a medium for transporting nutrients to the cells of the different body organs. It also carries waste products obtained from cellular metabolism to the lungs, kidneys, and liver for excretion (Benjamin, R.J. and McLaughlin, L.S., 2012). Other crucial roles of this blood component include transportation of all parts of the blood throughout the circulatory system, maintenance of normal blood pressure, and aiding heat distribution through the entire body.
Electrolytes are essential for the normal functioning of nerves and muscles. Calcium, potassium, sodium, chloride, and bicarbonate assist regulation of pH balance in the blood. Proteins make about 7% of the blood plasma, which plays different crucial roles in the body. Immunoglobulins are a vital class of proteins that supply protective antibodies in response to bacterial or viral antigens. Cytokines help in the regulation of inflammation and maintenance of normal blood cell formation. Coagulation proteins and their inhibitors play a crucial role in clotting, preventing excessive blood loss (Benjamin, R.J. and McLaughlin, L.S., 2012).
Other proteins' roles include carrying fatty acids and hormones, maintaining osmotic balance, carrying clotting factors, and providing viscosity to the blood.
