Is the destruction of RBCs caused by an antibody-antigen response?
lysis
What is the destruction of RBCs caused by an antibody antigen response?
Lysis is the destruction of red blood cells
What is the difference between relative and absolute anemia?
Relative = normal red blood cell count with a disturbance in regulation of plasma volume. ex- preganat women, athletes, post flight astronauts Absolute Anemia= Those types of anemia with an actual decrease in the number of red cells. Note: can be caused by a decrease production of RBCs or an increased destruction of RBCs
Why shivering occurs in case of malaria until a person is suffering from high fever?
A person suffering from malaria has those parasites entering into his RBCs by breaking the cells.Since several parasites are involved in the invasion there is a greater destruction of the RBCs which produces shivering
Where did anemia originate?
Anemia can have a number of causes, including inadequate production, excess destruction, or excessive loss of RBCs. It is found throughout the world.
How do antibodies kill the red blood cells?
Antibodies can lead to the destruction of red blood cells (RBCs) through a process known as opsonization and complement activation. When antibodies bind to antigens on the surface of RBCs, they mark these cells for destruction. This binding can activate the complement system, leading to the formation of membrane attack complexes that create pores in the RBC membrane, causing lysis. Additionally, phagocytic cells, like macrophages, can recognize and engulf the antibody-coated RBCs, ultimately leading to their removal from circulation.
Why wbc diluting fluid hemolyze rbc?
The distilled water present in the WBC diluting fluid is not isotonic and therefore is responsible for the destruction of RBCs. DR. Umesh Ghate and Shruti Salian
What is life span of a transfused Red blood cell?
The lifespan of transfused red blood cells (RBCs) is generally similar to that of naturally produced RBCs, which is about 120 days. However, the lifespan can vary depending on several factors, including the storage conditions of the blood prior to transfusion and the recipient's immune response. In some cases, transfused RBCs may have a shorter lifespan if the recipient's body recognizes them as foreign and begins to destroy them.
What is the significance of Enumerated?
low rbcs count shows anaemia high rbcs count show polycythemia vera. rbcs enumerations shows the bonemarrow how much active.
Why antigen present on red blood cell?
Antigens on red blood cells (RBCs) are molecules that can trigger an immune response if they are recognized as foreign by the immune system. These antigens, such as the ABO and Rh systems, play a crucial role in blood transfusions and organ transplantation, as they determine blood compatibility. The presence or absence of specific antigens on RBCs helps the body identify its own cells versus invaders, ensuring proper immune function and response.
What is the relationship between rapid rate of RBC destruction and jaundice?
When red blood cells are broken down rapidly, the heme component of hemoglobin is metabolized into bilirubin. If the rate of breakdown exceeds the liver's ability to process bilirubin, it can accumulate in the blood and tissues, leading to jaundice, a yellowing of the skin and eyes. This is seen in conditions such as hemolytic anemia or certain liver diseases.
Where are the rbc's made?
Red blood cells (RBCs) are primarily produced in the bone marrow, a spongy tissue found in the center of certain bones. In adults, this process mainly occurs in the vertebrae, ribs, sternum, and pelvis. The production of RBCs, known as erythropoiesis, is stimulated by the hormone erythropoietin, which is produced by the kidneys in response to low oxygen levels in the blood.
