Flashcards in Chapter 14: Immune System: Innate and Adaptive Immunity plus Microorganisms Deck (28):
1

Malady caused either by a microorganism or by an equivalent entity capable of both transmission between hosts and replication.

Infectious disease

2

Localized response within bodies to damage as well as to the presence of foreign materials within normally sterile tissues.

Inflammation

3

Mechanisms that protect an organism from pathogens and parasites and that do not change in their specificity over the course of the organism's lifespan.

Innate immunity

4

The production of antibodies along with T-cell mediated cellular cytotoxicity, both as a means of protecting organisms from pathogens and parasites.

Adaptive immunity

5

Relatively complex molecules, mostly proteins but also some carbohydrates, that can be recognized by adaptive immune responses.

Antigen

6

Proteins produced by vertebrate animals that function by binding to other molecules, thereby either inactivating those other molecules or tagging them as foreign to the body.

Antibody

7

The product of binding of an immunoglobulin to a protein or molecule that has been targeted by an immune response.

Antigen-antibody complex

8

Most common product employed for artificially acquired passive immunization.

Gamma globulin

9

White blood cell.

Leukocyte

10

Leukocyte capable of removing particles, microorganisms, and debris from extracellular environments within animal bodies

Phagocyte

11

Lymphoid organ found in the ventral cavity of vertebrates that functions to regulate various aspects of blood.

Spleen

12

Long-lived phagocytic leukocytes that also serve as antigen-presenting cells.

Macrophage

13

Relatively short-lived phagocytic leukocytes.

Neutrophil

14

Molecule playing a variety of roles in physiology, especially contribution to inflammatory responses but also playing roles in the regulation of the gastrointestinal tract as well as serving as a neurotransmitter.

Histamine

15

Collective name for B cells, T cells, and natural killer cells.

Lymphocyte

16

Gland in which cells responsible for cell-mediated immunity mature.

Thymus

17

Cytotoxic lymphocyte that is associated particularly with innate rather than adaptive immunity.

Natural killer cell

18

Lymphocytes that are responsible for producing antibodies.

B cell

19

B cells that are actively producing antibodies.

Plasma cell

20

Expanded clonal lineage of B cells that can be stimulated to produce plasma cells.

Memory cell

21

Adaptive immune responses that are dependent on B cell proliferation and associated biosynthesis.

Antibody-mediated immunity

22

Agent employed to artificially induce (or "prime") adaptive immune responses.

Vaccine

23

Means by which infected or otherwise abnormal body cells may be eliminated especially through the destruction of the infected cell.

Cell-mediated immunity

24

Lymphocytes that mediate cellular immunity (both helper and cytotoxic).

T cell

25

Molecules produced by virus-infected and other ailing cells that are used as a means of communicating that situation to other cells so that the latter can take protective actions.

Interferon

26

Lymphoid tissue exposed to the back of the mouth or pharynx.

Tonsils

27

Key site of development of adaptive immune responses, found in numerous, discrete locations throughout the body and that filter the drainage from body interstitium.

Lymph node

28

Means by which smaller foreign objects are slowly moved out of the respiratory system.

Mucociliary escalator
