E  It triggers fever.

A  by phagocytosis.

B  through injection of tumor necrosis factor

C  through insertion of perforins into the target’s membrane.

D  by releasing oxidizing agents.

E  by secreting antibodies.

A  Cytotoxic T-cells

B  Memory B-cells

C  Antibodies

D  Helper T-cells

A  After the first exposure to an antigen, memory B-lymphocytes are produced to recognize the same antigen upon a second exposure

B  The epithelium of the skin blocks most pathogens from ever entering the body

C  In the inflammatory response, mast cells produce histamine to facilitate the travel of immune cells and plasma to the afflicted area

D  A phagocyte engulfs and destroys bacteria, dead cells, and other potentially harmful particles that it encounters

B  Stimulated memory cells quickly engulf pathogens

C  The proper antibodies are constantly circulating in the blood

D  Pathogens are changed so they are no longer harmful

E  Innate defenses are strengthened

A  Antigen from the pathogen is presented simultaneously to memory helper T-Cells, memory T-cells, and memory B-cells

B  Antigen presenting-cells present antigens memory helper T-cells, followed by memory B-cells followed, by memory T-cells

C  Antigen from the pathogen is presented to memory helper T-cells to stimulate a new round of B-cell clonal selection and antibody response

D  Antigen from the pathogen is presented specifically to memory T-cells to activate cytotoxic T-cells to clear the infection

A  It enables many different antibodies to be made that all have different specificities of binding.

B  It helps in communication of antibodies with other components of immune system.

C  It helps the antibodies to function with very low affinity and specificity.

D  It enables many different antibodies to be made that all have same specificities of binding.
