When the antibodies in the patient's serum attack antigens on the erythrocytes in donor blood this is known as?
When the antibodies in the patient's serum attack antigens on the erythrocytes in donor blood, this is known as red blood cell incompatibility. Patients should receive blood with the same ABO and Rh(D) classification. A and B are dissimilar antigens on the red cells. The immune system recognizes antigens as foreign. O cells do not have A or B antigens.

What is the difference between antibodies and antitoxins?
Antibodies attach to antigens preventing them from attacking cells in the body. Antitoxins attack antigens and destroy them
Do antibodies attack extracellular or intracellular antigens?
Antibodies primarily target extracellular antigens, which are found outside of cells. These antigens can be on the surface of pathogens or released into the extracellular environment. Intracellular antigens, located inside cells, are primarily targeted by T cells of the immune system.
Why the A antibody of the AB recipient does not atack the donor A antigen on blood?
Having AB blood means you already have both A and B antigens in your organisms, so you DON'T have the antibodies, the A antigen doesn't affect the AB recipient 'cause it doesn't consider it as foreign (it's the same for the B antigen)
What is the difference between antibodies and antigens?
Antigen is a substance that can induce the generation of antibodies, any substance that can induce immune response. Antibody is a protective protein produced by the body in response to an antigen.
What forms in the blood to help fight invading antigens?
White blood cells, specifically lymphocytes, are responsible for helping to fight invading antigens in the blood. These cells produce antibodies that target and neutralize foreign substances, such as bacteria or viruses. Additionally, white blood cells can mount an immune response to destroy these antigens and prevent infection.
Molly has blood type A and her daughter has blood type B. Why can't Molly donate blood to her daughter?
Molly has blood type A, which means she has A antigens on her red blood cells and anti-B antibodies in her plasma. Her daughter, with blood type B, has B antigens and anti-A antibodies. If Molly donated blood to her daughter, the anti-B antibodies in Molly's blood would attack her daughter's B antigens, leading to a potentially dangerous immune reaction. Therefore, it is not safe for Molly to donate blood to her daughter.
What prevents mixing of blood?
The mixing of blood between different individuals, particularly in the context of transfusions, is prevented primarily by the presence of blood group antigens and antibodies. Each blood type (A, B, AB, O) has specific antigens on the surface of red blood cells and corresponding antibodies in the plasma. When incompatible blood types are mixed, the antibodies can attack the foreign antigens, leading to agglutination and potentially severe immune reactions. Additionally, the body's immune system plays a crucial role in recognizing and responding to foreign blood cells.
What white blood cells are responsible for recognizing and destroying foreign antigens?
The white blood cells responsible for recognizing and destroying foreign antigens are called lymphocytes. There are two main types of lymphocytes: B cells, which produce antibodies to tag antigens for destruction, and T cells, which directly attack and destroy cells that are infected or presenting foreign antigens.
What does it mean to have an ab blood type?
Blood can either be A, B, AB or O.This is differentiated by the antigen proteins on the cell. A has a antigens, b has b antigens, o has none, and AB has a and b antigens. You body also makes antibodies against what it doesn't have. So in your case, you have both and therefore dont create a or b antibodies. This makes you a universal acceptor. However, you can only donate to other AB people because if you give you blood to an A person, there body will attack the B antigens on your blood and same goes for B people.
Which blood type would a hospital find the most useful?
AB Neg is priorty followed by B Neg
How does a B cell tell the difference between an invader cell and a body cell?
Antigens work as bar-codes to help the immune system differentiate between body cells and pathogens. Normally the body will not attack its own cells, but is programmed to attack those with foreign antigens.
Are antigens produced by white blood cells and attack substances that may be harmful to the body?
Antigens are foreign proteins that your immune system can recognize as being harmful to your body, so it produces antibodies that memorize the antigen protein so it can launch an immune response if it ever again invades your body.
