Term
|
Definition
ability to destroy pathogens/foreigh materials
create antigens
Innate immunity
adaptive/acquired immunity |
|
|
Term
|
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 |
|
|
Term
|
Definition
| 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 |

Term
|
Definition
| determines level of specific antibody in patient’s blood |
|
|
Term
|
Definition
| contains antigen that elicits response like that of pathogen |
|
