What is the function of antibodies within the immune system?
Antibodies kill off any antigen that enters the body.
Antibodies are only made when you are given a vaccination for specific antigens.
Antibodies bind to specific antigens to flag for destruction.
Antibodies are part of an external defense mechanism.
How do Killer T-Cells differ from Plasma 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.
The blue molecule in this image is a(n) _______.
Antibody
Antigen
Pathogen
Blood cell
The orange molecule in this image is a(n) _______.
Antibody
Antigen
Antibiotic
Blood cell
These cells hep to activate or program certain cells in Humoral AND Cell Mediated Response
helper T cell
mast cell
cytotoxic T cell
plasma cells
A key part of the humoral immune response is
the attack of cytotoxic T cells on infected host cells.
the production of antibodies by plasma cells.
perforation of infected host cells by perforin.
the attack of phagocytes on living pathogens.
Secondary immune responses upon a second exposure to a pathogen are due to the activation of
memory cells.
macrophages.
stem cells.
B cells.
If a person has already had chicken pox, why do they generally not get sick a second time?
Memory B and T cells activate the immune system before the virus has a chance to make you sick
Natural killer cells recognize the pathogen quicker
Your 1st line of defense does a better job

None of the above
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
