How are antigens and antibodies involved in the bodys response to incompatible blood?
Antibodies are usually made in response to being exposed to an antigen. If you have had measles, then you have made antibodies to that antigen. Next time you are exposed, your body will fire up the antibodies and you will defeat the antigen (measles) quickly. You may feel some thing. You might say "I am coming down with something" but it will pass quickly.
In RBC, the genetic make up of the blood gives antibodies for each type. These are already in the plasma. There are antigens on each type of RBC.
1. Type A blood has antigen A on it's surface while antibody B is in the plasma. This person can be given A and a bad reaction will not occur as there is no antibody A in the plasma.
2. Type B has antigen B and antibody A in the plasma. Type B blood can be given but not A.
3. Type O has both antigens A and B and no antibodies for A or B. Only O can be given.
4. Type AB has no antigens on it's surface and both antibodies A and B. Types O, B, A, and AB can be given.
It is always desirable to give the same blood type. However, if it is very necessary, O can be given to all other blood types. It is called the universal donor.
AB can take any other blood type and is called the universal recipient.
To further complicate things RBCs also have an Rh factor and are called Rh+.
If not they do not, they are Rh-. These also should match. However O- is the actual universal donor.

How are antibodies and antigens related in the immune response?
Antibodies are proteins produced by the immune system in response to antigens, which are foreign substances that trigger an immune response. Antibodies bind to antigens to help neutralize or eliminate them from the body, playing a crucial role in the immune response.
The body's usual response to detection of antigens is to synthesize?
antibodies
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 plasma proteins is involved in neutralising antigens?
Immunoglobulins, specifically IgG antibodies, play a key role in neutralizing antigens by binding to them and enhancing their removal from the body. These proteins are produced by B lymphocytes in response to the presence of antigens.
How are antigens associated with antibodies?
Antibodies are produced in response to antigens. If you get infected with one of the 200 viruses that cause colds, these viruses are antigens and your body will respond by making antibodies. The antibodies will inactivate the virus. It usually takes 7-10 for the process to be complete.
How is anti e acquired?
Anti-E antibodies are acquired through exposure to foreign RBC antigens during pregnancy, blood transfusions, or organ transplants. These antibodies develop in response to incompatible red blood cell antigens of the Rh system, such as the D antigen. Anti-E is one of the many possible Rh antibodies that can be produced.
How do antibodies recognize antigens and initiate an immune response?
Antibodies recognize antigens by binding to specific molecules on their surface. This binding triggers a series of events that activate the immune response, including the production of more antibodies and the recruitment of immune cells to destroy the antigen.
What is the immune response that produces antibodies to kill pathogens and recognize them in the future?
Antigens
What is the role of antigens in the immune response to chickenpox?
The antigens cause an immune response leading to production of antibodies thereby causing the host to be resistant to subsequent infection
How are antibodies and antigens related?
Antibodies and antigens are closely related components of the immune system. Antigens are foreign substances, such as bacteria or viruses, that trigger an immune response, while antibodies are specialized proteins produced by the immune system to recognize and bind to specific antigens. This binding helps neutralize or eliminate the antigens, playing a crucial role in protecting the body against infections. Essentially, antibodies act as the body's defense mechanism against the threats posed by antigens.
What is the molecule in a person's body that is responsible for agglutination?
The molecule responsible for agglutination in a person's body is primarily antibodies, also known as immunoglobulins. These proteins are produced by B cells in response to foreign antigens, such as bacteria or viruses. When antibodies bind to these antigens, they cause clumping (agglutination), which facilitates the removal of pathogens by the immune system. Additionally, certain blood group antigens can also trigger agglutination in blood transfusions if incompatible blood types are mixed.
Which are specific molecules that are recognized by the body as foreign and to which antibodies bind known as?
Specific molecules that are recognized by the body as foreign and to which antibodies bind are called antigens. Antigens can be proteins, carbohydrates, lipids, or nucleic acids that stimulate an immune response when they enter the body.
