A protein, produced by the immune system that either attacks invading pathogens or marks them for killing.
Antibodies
Microbe
AIDS
Allergy
A secondary immune response will be faster when...
The individual has encountered the pathogen already
The individual's macrophages are on high alert
The individual has encountered the pathogen and has memory B cells circulating
Antibodies are produced by T cells
Which of one of these Immunoglobulin is dimer?
Ig M
Ig E
Ig D
Ig A
What is the function of B cell
Proliferate plasma cell and memory B cell
Release antibodies
Secrete interleukin-2
Produce interleukin-1
T lymphocyte is used in which immune response
Humoral Immune Response
Cell Mediated Immune Response
Antibody-Mediated Immune Response
What is the purpose secreting interleukin-2
To activate B cell
To activate Plasma cell
To activate Helper T cell
To activate
What happens after the second time you are exposed to a pathogen?
The body will not be able to fight off the pathogen quickly, because it knows how to get into the body easier.
The body's immune system will react the same was as it did during the first exposure.
The body can only be exposed to a pathogen a second time if you do not have a vaccine.
The body will know how to fight off the pathogen quickly, because memory cells have been created after the first encounter.
How do T cells differ from B cells?
T cells fight pathogens by killing pathogens directly, while B cells fight pathogens by making antibodies.
T cells only make memory cells, and B cells only make antigens
T cells fight pathogens by making antibodies, while B cells fight pathogens by killing pathogens directly.
T cells can only fight off pathogens the body has encountered once, and B cells can fight off any pathogen the body comes across.
What type of cell produces antibodies?
macrophage
cytotoxic T cell
plasma cell
Helper T cell
How does your body determine which cell to kill?
looks at the DNA fingerprint by each cell
uses the marker proteins
talks to the helper T cell about what to destroy
the brain tells it which cells belong
What is an antigen?
a protein that triggers an immune response
"hand cuffs" for pathogen
substance made by B cells
chemical that makes the immune cells divide
Which cell will "eat" pathogens?
helper T cell
B cell
macrophage
cytotoxic T cell
Largest immunoglobulin
Ig G
Ig M
Ig A
Ig D
What is the role of a cytotoxic T cell?
Kills infected cells
Helps activate other immune cells
Produces antibodies
Binds to antigens
A secondary immune response is more rapid than a primary one because
a booster injection contains many antibodies
killer T cells from the primary response are still in the blood
there are still memory B cells from the primary response
the B lymphocytes take a shorter time to be sensitized in the secondary response
Which best describes the relationship between antibodies and antigen?
One antibody can affect several different antigens.
Antibodies are specific to one antigen.
Antigens are produced in response to antigen.
Immunity develops when an antigen destroys an antibody.
A type of T cell that destroys infected cells is a:
cytotoxic (killer) T cell
helper T cell
memory T cell
suppressor T cell
Destroy infected cells and recognize cancerous cells
Helper T Cells
T cells for delayed hypersensitivity
Suppressor T Cells
Cytotoxic T Cells
B Cells differentiate into memory cells and this cell that secretes antibodies?
stem cells
nerve cells
helper cells
plasma cells
This cell activates cytotoxic T cells, other helper T cells as well as B cells
Helper T Cells
T Cells for delayed hypersensitivity
Suppressor T Cells
Cytotoxic T Cells
This type of immunity can be called nonspecific and refers to the bodies defenses that are present since birth.
resistance
adaptive immunity
acquired immunity
innate immunity
This type of immunity is acquired during one's lifetime. It is induced by antigens that invade the body.
innate immunity
adaptive immunity
nonspecific immunity
normal microbiota
