What is blood transfusion?
The procedure of putting blood components intravenously into someone's circulation is called a blood transfusion. To replenish missing blood components, transfusions are used to treat a variety of medical disorders. While early transfusions used complete blood, contemporary medical practice frequently just employs blood's constituent parts, such as red blood cells, white blood cells, plasma, clotting factors, and platelets.
Hemoglobin is found in red blood cells (RBC), which carry oxygen to the body's cells. Although white blood cells are not frequently used in transfusions, they are an essential component of the immune system and help the body fight illnesses. The "yellowish" liquid component of blood known as plasma serves as a lubricant and includes essential nutrients for the body's overall health.
