Helper T cells: A) produce antibodies B) can act as memory cells C) initiate both the cell mediated response and the humoral response D) all of the above

3)  Name each of these cells. A) These immune cells make antibodies.    B) These phagocytes destroy helminths and fungi and play a role in allergies. C) These lymphocytes play a role in the innate response to kill virally infected cells and cancer cells. D) These innate cells are phagocytes that present and activate T cells and activate wound repair. E) These granulocytes are the first cells from the blood to the site of infection.

Signs of inflammation due to a local hyperemia are caused by b) heparin c) phagocyte mobilization d) histamine e) complement production e) complement production

If a person is given a transfusion with the wrong blood type, what mechanism of action is responsible for the reaction seen in the body? O 1) IgE binds to mast cells releasing cytokines 2) Antigen-antibody complexes (IgG, IgM and IgA) lodge in basement membranes of tissues, neutrophil degranulation damages the tissues O 3) T cells respond to the inappropriate cells 4) IgG and IgM bind to cells stimulating complement, triggering cell lysis
