LYMPHATIC AND IMMUNE SYSTEM Flashcards
(36 cards)
the physiologic role of immune system
defend body against infectious microorganisms & pathogenic agents as well as non infectious foreign substance and transformed cells and their products
these includes cancer cells and any protein they produced
transformed cells
these include grafts or tissues coming from other human or organisms
noninfectious foreign substance
morphological counterpart of immune system
lymphatic system
the functional or physiological role of the lymphatic system
immune system
physiologic role or defense mechanism involve in fighting against foreign materials
immune system
one that performs the immune system
lymphatic system
state the two primary lymphatic organs stated in this chapter
thymus
bone marrow
Where the production & maturation of lymphocytes happens
primary lymphatic organs
primary cells involved in the lymphatic system
lymphocytes
serve as connecting frameworks for lymphatics or lymphocytes to travel te whole body
secondary lymphatic organs
first line of defense against microbial invasion
nonspecific (innate) immunity
nonspecific (innate) immunity is consists of
physical barriers
chemical barriers
secretory substances
state the physical barriers under innate immunity
skin
mucous membrane (lamina propria)
this aspect in innate immunity prevents foreign material or organism from invading deeper tissue
physical barriers
low pH of the stomach is due to
secretion of acidic ions such as hydrogen ions
low pH of the vagina is due to
commensal and mutual organism present in the vagina
true or false: Low pH equates to lower possible infections
true
as low pH (acidic) inhibit/destroy invading microorganism & prevent opportunistic pathogens
these neutralizes foreign microorganisms
secretory substances
state the secretory substances under innate immunity
fibronectin
lysozymes
interferons
complements
salivary substances
enzymes that are encapsulated or stored inside the granules of the neutrophils
lysozymes
what are the phagocytes present in the cells of the innate immune system
monocytes
neutrophils
macrophage
mast cells
basophils
eosinophils
natural killer cells
gamma/delta t cells
dendritic cells
these secretory substance are CYTOKINES which starts inflammatory reactions
fibronectins
interferons
complements
function of the phagocytes present in the cells of the innate immune system
responds immediately to infections/invading microorganism HOURS AFTER THE ANTIGEN EXPOSURE
