Blood and blood components are utilized in therapeutic settings for blood transfusion to save the lives of patients suffering from bleeding disorders, traumatic surgery, chronic illnesses, or uncommon blood diseases. Hemophilia A or B, sickle cell anemia, Von Willebrand disease, and other bleeding diseases necessitate blood transfusions. Patients who have been seriously injured in car accidents or other traumatic incidents such as violence and assault generally require traumatic surgery. Road accidents cause significant blood loss as well as bleeding, necessitating an emergency blood transfusion in these patients in order to maintain blood volume and save the patient's life. Furthermore, blood transfusion is essential in the treatment of chronic disorders such as blood cancer because large amounts of blood and blood cells are lost during cancer surgery. High dosages of chemotherapy are required for patients having stem cell transplantation for the treatment of blood malignancies such as leukemia, myeloma, lymphoma, and others, which results in blood cell depletion. Plasma donation is also necessary for maintaining the body's levels of immunoglobulin, an antibody protein that ensures the immune system's normal functioning.
What is blood and components of blood?
Blood is a unique type of bodily fluid. Plasma, red blood cells, white blood cells, and platelets are the four primary components. The transfer of oxygen and nutrients to the lungs and tissues is one of the numerous functions of blood. To avoid excessive blood loss, blood clots are formed.
What are the components of blood?
RBCs are red blood cells (erythrocytes). These are the vessels that transport oxygen from the lungs to the rest of the body.
WBCs are white blood cells (leukocytes). These aid in the immunological process and aid in the battle against infections.
Stem cells are the precursors of blood cells generated in the bone marrow. The first phase of all blood cells is the stem cell (or hematopoietic stem cell). Several different cells emerge as the stem cell grows. Red blood cells, white blood cells, and platelets are examples of these. Blasts are a kind of immature blood cell. Some blasts develop in the bone marrow. Others migrate to different places of the body to grow into fully functional blood cells.
