Most of the lymph enters the blood stream into which vessel?
left subclavian vein
The only organs to filter lymph are
lymph nodes
The only lymphatic organ to filter blood is
spleen
The lymphatic organ that produces hormones and is involved in maturation of T lymphocytes is
Thymus
The bactericidal enzyme secreted in mucus membranes is
lysozyme
The enzyme secreted by certain pathogens in that can dissolve the viscous ground substance in areolar tissue is
hyaluronidase
The release of superoxide (02-), hydrogen peroxide (H2O2), and hypocholorite ion HCLO-, by neurtrophils is referred to as a
respiratory burst
Type of leukocyte with antiparasite activity and is also linked to allergic response
eosinophils
Lymphocyte that is active in nonspecific attack against viral or bacterial infected cells
NK cells
Circulating leukocytes that are precursors to macrophages
monocytes
Inflammatory leukocyte that releases histamine and heparin and attracts other WBCs to the area of inflammation
basophils
Process of leukocytes adhering to wall of blood vessel
margination
Process of leukocytes squeezing through capillary walls
diapedesis
Type of leukocyte that is quickest to respond and begin phagocytosis
neutrophil
Phagocytic leukocyte that is the second to respond to an area of infection (8-12 hours)
macrophage
Factor released by endothelial cells and platelets that stimulates fibroblasts to begin synthesizing collagen
Platelet derived growth factor
Polypeptide secreted by virally infected cells that has protective effect on surrounding cells
interferon
Group of 20 enzyme like proteins in the blood that enhance inflammation and antimicrobial activity
complement protein
Covering of bacterial surface that permits or enhances phagocytosis by macrophages
opsonization
Protein produced by macrophages that stimulates the hypothalamus to secrete PDE which leads to fever
pyrogen
Antibody mediated specific immunity
humoral immunity
Molecules that can evoke an immune response and are usually (but not always) proteins
antigen
Area on antibody that binds foreign materials
variable region
Class of antibody that is a pentamer and is involved in the initial immune response
IgM
Class of antibody that is involved with secondary immune response and is the most abundant of the antibodies
IgG
Class of antibodies involved in secretions such as tears, saliva and intestinal juices
IgA
Antibody action that causes the antigen and antibody to form a solid particle that can be phagocytosed
precipitation
Hormone like messengers between lymphocytes
lymphokine
Type of lymphocyte involved in humoral immunity
B cells
Active antibody producing cells in blood
plasma cell
Type of lymphocyte that is directly involved in attacking viral infected cells
killer T cell
Type of lymphocyte that is involved in the activation of both the cell mediated and humoral immunity
helper T cell
Type of cells that can activate B lymphocytes and cytotoxic T lymphocytes by bringing them antigen fragments
antigen presenting cell
Type of cell mediated cell that forms clones for future exposure to antigens
memory cells
Type of lymphocytes that can limit the attack of the immune system by releasing inhibiting lymphokines
suppressor T cell
Type of self antigen found on macrophages and other APCs
MHC-2
Type of self antigen found on all nucleated cells
MHC-1
Type of MHC antigen that is recognized by CD4 receptors
MHC-2
Type of lymphocyte that has CD8 receptors
cytotoxic T cell
Costimulator provided by macrophages to helper T cells
interleukin 1
Costimulator provided by macrophages to helper T cells
interleukin 1
Function of lymphotoxins produced by the killer T cells
destroy DNA
Chemical released by killer T cells that punch holes in virally infected cell
perforin
Factor produced by killer T cells that destroys cells infected by cancer
tumor necrosis factor
Type of T cell that slows down the immune response
suppressor t cell
Type of immunity that is transmitted from mother to fetus
natural passive
Type of immunity that is developed from a vaccination
artificial active
Type of immunity that is developed from a vaccination
artificial active
Type of immunity developed after having a disease
natural active
Factor released by killer T cells that attracts macrophages to the area of attack
MAF
Type of antibody involved in the agglutination of red blood cel
Ig M
Enzyme used by retroviruses to plant genetic material of the virus into the host’s genome
