Term
basophils
Definition
least numorous leukocytes, classified as a granulocyte, releases histamine andheparin at the site of tissue damage
Term
Neutrophils
Definition

function is phagocytosis(ingest pathogens and cellular debris) Originate in bone marrow, are the most common leukocyte (granulocyte).

Are the first responders

they release chem. that increase tissue damage and inflammation, stimulating immune response

Term
Eosinophils
Definition
there function is to break down the chem. released by the basophils and mast cells, slowing or stopping the inflammatory response. They fight the invasion of parasitic worms and are part of innate immunity
Term

Monocytes

Definition
agranulocyte, active in immune defense at a later stage, phagocytosis 
Term
T Lymphocytes
Definition

cytotoxic T cells (cell poison)

helper T cells (adaptive immunity)

memory T cells (remember pathogens)

Term
B Lymphocytes
Definition

responspart of adaptive immunity known as antibody mediated immunity.

Plasma cells (produce antibodies to nonself-antigens)

Memory B cells (remember pathogens)

Term
Interferon
Definition
a cytokine produced by cells that have been infected by a virus
Term
cytokines
Definition
are proteins produced by damaged tissues and WBC that stimulate the immune response. Involved in innate and adaptive immunity
Term
what triggers the hypothalmus to raise the body's temp. set point?
Definition
cytokines stimulate the hypothalamus
Term
Innate Immunity
Definition
destroys anything nonself
Term
Adaptive Immunity
Definition
this part of immunity has memory and attacks specific pathogens
Term
graves disease
Definition
effects the thyroid gland
Term
addisons disease
Definition
effects the adrenal gland
Term
myesthenia gravis
Definition
acetylcholine receptors in skeletal muscle
Term
thoracic duct
Definition
the lumbar, intestinal, and intercostal trunk all empty here
Term
thymus
Definition

packed with lymphocytes that eventually become

T Lymphocyts, can dissappear in adults, secretes hormone that stimulates maturation of

T Lymphocytes in the lymph nodes
