AP Immunity

What attacks microbes indiscriminately?

• The adaptive immune system

• The innate immune system

• The lymphatic system

• The nervous system

Which are NOT part of the adaptive immune system?

• B cells

• Helper T cells

• Cytotoxic T cells

• Monocytes

What type of cell produces antibodies?

• B cells

• Macrophages

• Un-myelinated neurons

• Antigen-presenting cells

What type of cell kills invading cells directly?

• Helper T Cells

• Cytotoxic T Cells

• B cells

• Cytokines

If our body encountered an antigen for the first time, what would occur?

• B cells would be unable to make antibodies until antigens are presented through macrophage MHCs

• Antibodies would not exist until dendritic cells brought pathogens to the lymph nodes

• Immunity would be at its highest because antibodies for this specific antigen have not yet been depleted

• In order to make up for the deficit in B cell antibody production, helper and cytotoxic T cell production would increase

What correctly describes antibodies?

• They can attach to many different antigens

• They are a part of the innate immune system

• They are specific to their antigens

• They are found on invasive bacteria

Why is the lymph node important to the immune system?

• It is where dendritic cells bring pathogens to activate B cells to produce a specific antibody

• It is where Helper T cells carry antigens in order to activate the innate immune system

• It is the control center of the innate immune system because it produces macrophages

• It is a vestigial organ which was important in ancestral immunity, but now serves no function.

Foreign molecules carry

• antigens

• antibodies

• B cells

• helper T cells

What ligand is released by helper T cells?

• Neurotransmitter

• Antibodies

• HIV

• Cytokines

What do Helper T cells and Cytotoxic T cells have in common?

• Both release cytokines

• Both carry antigens

• Both carry T cell receptors

• Both kill infected cells
