Adaptive Immunity

Humoral immunity refers to the immunity provided by:

• Helper T cells

• Cytotoxic T cells

• B cells

• Macrophages

• Memory T cells

Cell-Mediated immunity refers to the immunity provided by:

• Helper T cells

• Cytotoxic T cells

• B cells

• Macrophages

• Memory T cells

Match the following cells types to their description.

• take in and display a portion of the antigen for other immune cells to recognize

• Cytotoxic T cells

• stimulate other cells of the innate and adaptive immune systems

• Plasma Cells

• can become memory or plasma cells

• Helper T cells

• release antibodies

• Antigen-presenting cells

• directly kill the pathogen or the pathogen infected cell

• B cells

Which cells of the immune system can generate memory cells that last for decades?

• B cells

• T cells

• macrophages

• dendritic cells

• plasma cells

Which cell of the adaptive immune system matures in the bone marrow?

• B cells

• T cells

Which cell of the adaptive immune system matures in the thymus?

• B cells

• T cells

Which cell only stimulates other immune cells and causes division of cytotoxic T cells and B cells, but does not kill any pathogens directly?

• macrophage

• neutrophil

• plasma cell

• Helper T cell

Each T cell can recognize:

• any antigen

• only one specific antigen presented by an APC

• antibodies

• B cells

How does a helper T cell know which cytotoxic T cells and which B cells to stimulate?

• whichever T cells/B cells match the antigen that's being fought

• it's random

• whichever T cells/B cells are closest in location to the helper T cell will be stimulated

Match the cells to the arm of the immune system they belong to.

macrophages = ​ (a)  

T cells = ​ (b)  

B cells = ​ (c)  

antigen presenting cells like dendritic cells = ​ (d)  

natural killer cells = ​ (e)  

• innate immune system
