How do antibodies react to antigens?
Type B antibodies react to type B antigens by begining to clump together, and the clumps may block blood vessels.
What is the clumping together of RBCs by antibodies?
coagulation- is not the correct answer! The correct answer from my "Anatomy and Physiology" book is Agglutination
What is an autoagglutination?
An autoagglutination is the clumping together of an individual's red blood cells by his or her own serum due to being coated on the surface with antibodies.
List and describe 4 ways antibodies aid in immunity?
There are four types of antibodies that aid in immunity. The Lysins bind the antigens therefore causing them to disintegrate. The Agglutinins bind the antigens causing the micro-organisms to clump together. The Antitoxins bind the toxins therefore making them harmless to the body. The Opsonins bind the antigens on the outer surface.
3 ways that antibodies help destroy pathogens?
The antigen itself cannot destroy the pathogen but here are three ways it helps out:1. Antibodies can clump antigens together in order to enhance phagocytosis2. Antibodies can activate the cytotoxic cell responses (a chemical that destroys antibody-bound antigen).3. Antibodies can activate B lymphocytes, which results in the production on plasma and memory cells.
What does the term clumping refer to?
The term clumping refers to a collection of objects that get stuck together either due to small spaces or blockages. Some examples are leaves clumping together or red blood cells clumping together.
What are the purpose of agglutination test?
Agglutination serves to provide an idea of the presence of certain antibodies within the body. If specific antibodies against the antigen are present, the antibodies will combine with the antigens, coat the cells and cause the cells to join together, or agglutinate. It can be used to identify unknown antigens in diagnosing infections and to determine matching tissue types and blood groupings between two individuals.
How do you B cells help defend the body against pathogens?
B cells make antibodies that grab on to the antigens and make them clump together then something eats them.
What role do antigens normally play in the human body?
are antigen apart of the body's natural defense against infections
Can antigens trigger a response of the immune system?
Anti gens bind to viruses/bacteria that 'fit' them, clumping together and allowing phagocytosis. They tend to be specific to one strain hence why we cannot vaccinate against a virus that mutates frequently or has many strains.
The process of cells clumping together is known as?
agglutination
When does acute poststreptococcal glomerulonephritis develop?
after certain streptococcal bacteria (group A beta-hemolytic streptococci) have infected the skin or throat. Antigens from the dead streptococci clump together with the antibodies that killed them. These clumps are trapped in the kidney tubules
