Kathy Ramirez Per.2 Immune System
Major functions of the Lymphatic & Immune systems
Immune system
protect body from harmful substances
keeps record of every germ
prevent disease
Lymphatic system
defend body against infections
drain lymph throughout body
keep body fluids in balance
Purpose and examples of First, Second and Third line of defense
2nd line
not targeting specific individuals
phagocytic cells ingest/destroy microbes
destroy invaders
EX
inflammation
fever
recognition
non specific resistance
3rd line
get rid of previous pathogen
EX
dendritic cells in body tissue
memory cells
eliminate specific pathogen
1st line
against germs entering body
beneficial bacteria on skin stops bad bacteria
sense wounds or traumas
EX
tears
mucus
skin
stomach acid
Innate immune defenses and Adaptive immune defenses
innate
born with it
form 1st line of defense
prevent movement or spread of pathogens
adaptive
differentiation of self from non-self
tailor response to particular foreign invader
antibodies and lymphocytes
Location of Lymphatic organs and their functions
location
chest
abdomen
armpit
groin
throat
function
T lymphocytes mature in thymus
produce blood and immune cells
nodes and spleen filter out pathogens
Passive vs. Active immunity
passive
no work to develop it
immediate protection
directly given antibodies
active
vaccinations
exposed to something making IS produce antigens
takes time to develop
Humoral response and cellular response
Cellular response
takes longer
target bacteria and tumor cells
antigens from pathogens circulating freely
CD2, CD3, CD4, CD8,
Humoral response
B cells differenciate to B plasma
Helper T cells assist
specific antibodies
CD40, CD21, and Fc
Artificial vs. Naturally acquired immunity
natural
antibody from another organism
breastfeeding a baby
exposure to disease
artificial
blood transfusions
killed or weakened form of disease
vaccine induced
Disorders associated with the Immune system
diabetes
little to no inuslin
Immunodeficiency
absence of elements needed in IS
asthma
disease affecting lungs
Cells involved in the immune system and their functions
neutrophils
eosinophils
basophils
