Hypersensitivity rxn that occurs when an antigen on a cell surface binds with an antibody and is
then recognized by the body as being foreign. Macrophages or dendritic cells then recognize the
cell and "present the antigen" which then causes B cell proliferation and production of IgG and
IgM antibodies. The antibodies bind to the cell and activate the complement cascade
CORRECT ANSWER-Type II
Hypersensitivity rxn that occurs when there are more antigens than there are antibodies. The
antigens float around in the circulation and multiple antigens may bind one antibody, thus
forming an immune complex. CORRECT ANSWER-Type III
Hypersensitivity rxn that is cell-mediated. Cytotoxic CD8+ T cells and CD4+ helper T cells
recognize antigen that is in a complex with major histocompatibility complex 1 or 2. This results
in proliferation and activation of the cells. Activated CD8+ T cells then destroy the antigen
containing cells while activated macrophages release hydrolytic enzymes. CORRECT
ANSWER-Type IV
