lymphatic and immune system functions
lymphatic system
immune system
return clean fluid and leaked proteins back to blood
drain excess fluid from tissue
essential role in body's defense/resistance to diseases
bodys defense against infectious pathogens
keeps pathogens out and attacks those that enter body
anatomy of the lymphatic system
network of vessels that assist in circulation
lymphatic vessels collect and carry away excess fluid
organs, cells, and biochemicals help defend against disease
innate immune/adaptive immune
adaptive
naturally acquired active immunity - occurs after exposure to antigen
artificially active immunity- occurs through vaccines without becoming ill from the disease
naturally acquired passive immunity - antibodies are passed from mother to fetus
artificially acquired passive immunity- involves injection from gamma globulin containing anti bodies
innate
skin
epithelial
mucous membrane surfaces
humoral/cellular response
cellular
t cell activation requires presence of antigen
t cell needs to be activated by macrophage
active t cells interact directly with antigen
t cells begin to recognize the virus
synthesize and secrete cytokins
helper cell stimulates b cell to produce antibodies for antigen
humoral
b cell becomes activated and produces clone
helper t cell releases cytokines
some b cell may have plasma through producing/secreting antibodies
some memory b cell respond to future antigen
antibody immediate immune response
antigen/antibodies
antibodies
soluable proteins secreted by plasma cellls
carried by body fluids
major antibodies are IgG, IgA, IgM, IgD, IgE
actions of antibodies- complement fixation, opsonization, neutralization, agglutination, precipitation
antigen - toxin/foreign substance that induces immune system
cells involved in the immune system
t cells- direct destruction; involved in cell mediated immunity
b cells- secreted antibody indirectly; humoral/antibody mediated immunity
immune disorders
HIV
human immunodeficiency virus
virus and infection- can be transmitted by unprotected sex, unsterilized needles, pregnancy/birth/breastfeeding, blood transfusion
AIDS
Acquired immunodeficiency syndrome- is a stage not a disease
