Correct Answer: granulocytes

Number 2. white blood cells without granules

Correct Answer: agranulocytes

Number 3. type of white blood cell that engulfs and digests by phagocytosis cellular debris, foreign substances, microbes, cancer cells, and anything else that does not have the types of proteins specific to healthy body cells on its surface

Correct Answer: macrophages

Number 4. the type of stem cell from which basophils, eosinophils, and neutrophils originate

Correct Answer: myeloid

Number 5. type of stem cells that all blood cells, including white blood cells, originate

Correct Answer: hematopoietic stem cells

Number 6. a protein molecule capable of inducing an immune response

Correct Answer: antigen

Number 7. a process in the body's immune system by which dendritic cells capture pathogenic antigens, and then present them to the immune system for activation

Correct Answer: antigen-presentation

Number 8. ingest and destroy all microbes that pass into body tissues

Correct Answer: phagocytic cells

Number 9. first cells to reach an area where a breach in the body has been made as in a cut; yellow engulfing bacteria

Correct Answer: neutrophils

Number 10. phagocytosis of any dead body cell and bacteria; digests large foreign particles in a wound

Number 11. work by releasing toxins from their granules to kill pathogens. Attach to and help immobilize invaders.

Correct Answer: eosinophils

Number 12. have the ability to secrete anticoagulants (keep blood from clotting), and antibodies that have function against hypersensitivity reactions in the bloodstream. Help to bring more immune cells to infection site by releasing histamine, which dilates the vessels.

Correct Answer: T cells

Number 17. type of lymphocyte that releases antibodies and assist in T cell activation; develop and mature in the bone marrow

Correct Answer: B Cells

Number 18. they activate B cells and killer T cells

Correct Answer: Helper T Cells

Number 19. type of T cell that destroys invaders targeting virus-infected cells and tumor cells

Correct Answer: Killer T Cells

Number 20. produce antibodies that so that they can seek out intruders and deactivate them for other cells to destroy

Correct Answer: plasma cells

Number 21. can "remember" specific intruders so that the next time an intruder tries to invade the body, it is wiped out before causing symptoms

Correct Answer: B memory cells

Number 22. excessive numbers of white blood cells

Correct Answer: leukocytosis

Number 23. insufficient numbers of white blood cells

Correct Answer: leukopenia
