____________ are responsible for the production of antibody against free pathogens and soluble products from pathogens while ____________ destroy pathogen and virally infected cells and abnormal cells.

The significance of the major histocompatibility complex (MHC) in the immune response:

A. Serves to minimize autoimmunity or “self-reactivity” of the immune system
B. Serves to present fragments of antigens to T cells
C. Used by helper T cells to regulate the expansion of antibody producing B cells
D. All of the above

The lack of an immune response to self is called:

A. Autoimmunity
B. Tolerance

Humoral branch, cell-mediated branch, or both:
Involves B cells

Humoral branch, cell-mediated branch, or both:
Involves T cells

Humoral branch, cell-mediated branch, or both:
Responds to extracellular bacterial infection

Humoral branch, cell-mediated branch, or both:
Involves secreted antibody

Humoral branch, cell-mediated branch, or both:
Kills virus-infected self cells

Innate immunity or adaptive immunity: Is the first to engage upon initial encounter/ antigen

Innate immunity or adaptive immunity: Is the most pathogen specific

Innate immunity or adaptive immunity: Employs T and B lymphocytes

Innate immunity or adaptive immunity: Adapts during the response

Innate immunity or adaptive immunity: Responds identically during the first & second exposure to the same antigen

Innate immunity or adaptive immunity: Responds more effectively during a subsequent exposure

Innate immunity or adaptive immunity: Includes a memory component

Innate immunity or adaptive immunity: Is the target of vaccination

Innate immunity or adaptive immunity: Can involve the use of PAMP receptors

Innate immunity or adaptive immunity: Involves antigen-specific receptors binding to pathogens

Innate immunity or adaptive immunity: Can be mediated by antibodies
