Immunity Flashcards
(10 cards)
What is Adaptive Immunity?
A type of immunity that adapts and learns to provide long-lasting protection against specific invaders.
Adaptive immunity is crucial for effective immune response and memory.
What is Antibody-Mediated Immunity (AMI)?
A type of adaptive immunity that uses antigen-antibody interactions to neutralize, eliminate, or destroy invaders.
AMI is characterized by the production of antibodies by B-cells.
What are antibodies?
Proteins known as immunoglobulins produced by B-cells that bind to specific antigens to destroy them.
Antibodies play a vital role in the immune response.
How does the body adapt in Antibody-Mediated Immunity?
The body learns how many antibodies to make to provide long-lasting immunity to a specific invader.
This process is essential for immunity against recurrent infections.
What are the two types of AMI?
Active and passive immunity.
Active immunity involves the body producing its own antibodies, while passive immunity involves receiving antibodies from another source.
What type of immunity occurs when a child receives the MMR vaccine?
Active immunity.
Vaccines stimulate the body’s immune response to produce antibodies.
What type of immunity occurs when a person receives convalescent serum for COVID-19?
Passive immunity.
Convalescent serum contains antibodies from a recovered patient.
What type of immunity occurs when a person is infected with chicken pox?
Active immunity.
The body produces antibodies in response to the infection.
What type of immunity does an infant receive through colostrum?
Passive immunity.
Colostrum is rich in antibodies and provides initial protection to the infant.
What type of immunity occurs when a patient is given an antiserum for an exposure to rabies?
Passive immunity.
Antiserum provides immediate antibodies to neutralize the virus.
