Definition
chemical markers that identify self vs. non-self |

Term
|
Definition
Non-specific has no memory response is always the same |
|
|
Term
|
Definition
specific to a target may involve antibodies creates immunity becomes more effective over time |
|
|
Term
|
Definition
does not produce antibodies involves T cells (3 types): helper T cells (CD4) cytotoxic (killer) T cells (CD8) memory T cells |
|
|
Term
Antibody mediated immunity |
|
Definition
produces antibodies involves B cells |
|
|
Term
|
Definition
blood plasma that has been filtered through blood capillary walls, through interstitial fluid, and into the lymphatic vessels; a clear fluid contained in lymphatic vessels and tissues |
|
|
Term
|
Definition
larger in diameter than blood capillaries; very permeable, allowing fluid to flow into them but not out; found in most tissue spaces |
|
|
Term
|
Definition
tube-like structures that carry lymph; smooth muscle & one-way valves prevent backflow |
|
|
Term
|
Definition
oval structures located along lymphatic vessels storage for T and B cells, plasma cells and macrophages masses of lymphatic tissue foreign material phagocytized by fixed macrophages before returning to blood |
|
|
Term
|
Definition
Cervical: drains head & neck Axillary: arm pits |
|
|
Term
|
Definition
Smaller than nodes Beneath epithelium of mucous membrane Near openings to environment Tonsils |
|
|
Term
|
Definition
pair of almond-shaped masses each located behind the nose and on the roof on the posterior wall of the pharynx; AKA adenoids |
|
|
Term
|
Definition
pair of tonsils each located in the back of the mouth on the lateral walls of the pharynx; AKA tonsils |
|

Term
|
Definition
mass of lymph tissue near the root of the tongue |
|
|
Term
|
Definition
plasma cells that produce antibodies macrophages phagocytize pathogens & old RBC’s storage of platelets production of blood cells (hemopoiesis) during fetal life |

Empties to rt. subclavian vein |
|
|
Term
|
Definition
Empties to left subclavian vein |
|
|
Term
|
Definition
No pump to force movement Movement is caused by breathing and by skeletal (smooth) muscle contractions Movement is slow, one-way valves prevent backflow |
|

Term
|
Definition
make direct contact w/pathogens & tumor cells Inflammation |
|
|
Term
|
Definition
helper T cells (CD4) recognize foreign vs. self Cytotoxic (killer) T cells (CD8) chemically destroy antigen Memory T cells remember antigen |
|
|
Term
|
Definition
involves B cells Differentiate into plasma cells, then produces antibodies Form Memory B cells – rapidly respond to previously seen antigens Antibodies bond to antigen and label for destruction |
