[DOCUMENT TITLE]
Neutralization
prevention of microbial attachment to host cells
Opsonization
promotion of microbial phagocytosis and clearance
complement
Targeting of microbial destruction by soluble molecules or by leukocytes
Cytotoxic CD8 T cells
MHC Class I presents antigens to which T cells
Helper CD4 T cells
MHC Class II presents antigens to which T cells
IgA
Found in mucous, saliva, tears, and breast milk. Protects against pathogens
IgD
Part of the B cell receptor. Activates basophils and mast cells.
IgE
Protects against parasitic worms. Responsible for allergic reactions
IgG
Secreted by plasma cells in the blood. Able to cross the placenta into the fetus
IgM
May be attached to the surface of a B cell or secreted into the blood. Responsible for early stages of immunity.
primary lymphoid organs
Where immune cells develop
secondary lymphoid organs
where the immune response is initiated
Bone Marrow
Soft, spongy tissue that has many blood vessels & is found in center of most bones
Yellow Bone Marrow
