Antibodies binds to specific region in an antigen. Antibodies recognizes the part of an antigen and binds to specific region. Part of an antigen recognised by the antibody and binds is know as Antigenic Determinant or Epitope.
Antibodies are generated by a sub set of immune cells called B cells. The main receptor for these cells are antibodies, although while they're bound to the surface of the B cell they are called B Cell Receptors (BCRs). While these cells are developing the BCR genes undergo a number of mutations, these mutations define the antigen binding region, which as described above, binds to the antigen. In fact there are so many possible ways the BCR genes can mutate that we can recognize a nearly infinite number of antigens.
Then once your body has encountered an antigen the B cells that have BCRs that can react with the antigen begin to proliferate, and then they start excreting antibodies. After the infection is over, B cells will continue to refine they antigen specificity, that way when they encounter the infection again they can respond with much more specific antibodies and more quickly, this process is called affinity maturation.

To what do antibodies attach on the pathogen?
Antibodies attach to specific antigens on the surface of pathogens.
What are the antigens and antibodies for each blood type?
Blood types are defined by specific antigens and antibodies present in the blood. Type A has A antigens on red blood cells and anti-B antibodies; Type B has B antigens and anti-A antibodies; Type AB has both A and B antigens with no antibodies; and Type O has no A or B antigens but has both anti-A and anti-B antibodies. This immunological distinction is crucial for safe blood transfusions and organ transplants.
What is specific immunity?
specificity the quality of having a certain action, as of affecting only certain organisms or tissues, or reacting only with certain substances, as antibodies with certain antigens (antigen specificity).
Serological testing is based on the fact that antibodies react specifically with an anigen all bacteria have the same antigens or the human body makes antibodies against bacteria?
AnswerThe human body makes specific antibodies to specific antigens (ex. proteins on a bacterial membrane) that it encounters. Bacteria do not all have the same antigens.* antibodies react specifically with an antigen
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.
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.
What medical term specialized white blood cells that produce antibodies coded to specific antigens?
all wbc produce antibodies to attach the the pathogens antigens.
To which specific part of the pathogen do antibodies attach?
Antibodies attach to specific proteins on the surface of pathogens, called antigens, to help neutralize and eliminate them from the body.
Do B cells have antibodies on their surface?
Yes, B cells have antibodies on their surface that help them recognize and bind to specific antigens.
Which antibody and antigen combination match each blood type?
The blood type notation A Rh- indicates which antigens and antibodies are present in the blood. A indicates there are A antigens. Rh+ indicates there are Rh antigens. B antibodies. If there are A and Rh antigens but no B antigens, the antibodies in the blood plasma are B antibodies.
Can antibodies bind to multiple antigens simultaneously?
Yes, antibodies can bind to multiple antigens simultaneously.
A complement cell is capable of producing and secreting antibodies that are coded to destroy specific antigens?
No
