16
Q

Immune system

A

The collection of organs, cells, tissues, and molecules that mediate the immune response

17
Q

Immunity

A

The body specific protective response to a foreign agent organism; resistance to disease, specifically infectious diseases

18
Q

Immunopathology

A

Study of diseases resulting in dysfunctions within the immune system

19
Q

Immuno regulation

A

Complex system of checks and balances that regulates or controls immune responses

20
Q

Immunosenscenence

A

The gradual deterioration of the immune system brought on by the aging process

21
Q

Interferons

A

Proteins formed when cells are exposed to viral or foreign agents; capable of activating other components of the immune system

22
Q

Lymphokines

A

Substances released by sensitized lymphocytes when they come in contact with specific antigens

23
Q

Memory cells

A

Cells that are responsible for recognizing antigens from previous exposure and mounting an immune response

24
Q

Natural killer cells NK

A

Lymphocytes to defend against microorganisms and malignant cells

25
Q

Null lymphocytes

A

Lymphocytes that destroy antigens already coded with the antibody

26
Q

Opsonization

A

The coating of antigen/antibody molecules with a sticky substance to facilitate phagocytosis 

27
Q

Phagocytotic cells

A

Cells that engulf, ingest and destroy foreign bodies are toxins

28
Q

Phagocytotic immune response

A

The immune system’s first line of defense, involving white blood cells that have the ability to ingest foreign particles

29
Q

Stem cells

A

Precursors of all blood cells; reside, primarily in the bone marrow

30
Q

Suppressor T cells

A

Lymphocytes that decrease B cell activity to a level at which the immune system is compatible with life

31
Q

T cells

A

Cells that are important for producing a cellular immune response
