Immune System Flashcards
immune system definition
network of cells, tissues, organs, and molecules that work together to protect the body from invasion by pathogenic organisms
immunology definition
study of the immune system, immune response, and diseases occurring due to inadequate functioning of immune system
what cells are part of the immune system
white blood cells/leukocytes
(macrophages, dendric cells, mast cells)
what tissues are part of the immune system
blood
bone marrow
tonsils
mucous membranes
major organs of the immune system
lymph nodes
lymphatics
thymus
spleen
peyers patch
tonsil
sppendix
what molecules are pert of the immune system
antibodies
cytokines
complement
what are antibodies
cytokines produce by immune cells
what are the three main parts of blood
plasma
whit blood cells/platelets
red blood cells
whats held in plasma
antibodies
complement
cytokines
what cells are held in blood
neutrophiles
lymphocytes
monocytes
basophils
eosinophils
what cells are in tissues
dendritic cells
macrophages
mast cells
where are B-lymphocytes and all blood cells produced
bone marrow
where do T-lymphocytes develop
Thymus
what is the job of the lymphatic system
bring fluid from tissues into vena cava
characteristics of the lymphatic system
-unidirectional
-no pump/works from natural muscle movement
three layers of bodies defense
-physical/mechanical, chemical, and microbial
-innate immunity
-adaptive immunity
what is mucociliary clearence
movement of mucus within the body to help move debris to exits
what 3 microbes can be grown in a lab for probiotics
saccharomyces boulardii
bifidobacterium
lactobacillus
what level of recognition does innate immunity have
groups of pathogens(bacteria vs. virus vs. fungi etc)
what level of recognition does adaptive immunity have
unique molecular features of each different pathogen(virus vs. virus)
T/F adaptive immunity is always present
FALSE. it must be activated by innate immunity and enhances the killing mechanism of innate immunity
which species type red blood cells contain nuclei
avian
innate immunity molecular components
cytokines
complement
roles of innate immunity
control infection during time it takes to engage adaptive immunity(5 days)
activate and direct adaptive immunity
T/F innate immunity leads to lasting immunity
FALSE
T/F adaptive immunity leads to lasting immunity through immunological memory
TRUE
adaptive immunity cellular components
B cells
T cells
adaptive immunity molecular components
antibodies
cytokines
hematopoiesis
the process of formation of blood cells from bone marrow derived stem cells
T/F cells for adaptive immunity are produced at a different location than cells for innate immunity
FALSE they are all produced from stem cells
phagocytosis in immune response
binds to bacteria to cause its mass exit from body
what are cytokines
small glycoproteins secreted by cells for communication
