Immune system Flashcards
Antibodies attach to
One specific pathogen
Antibodies are part of
Specific immune system response
Vaccines stimulate body to make
Antibodies
Epitope
Chemical signal on the outside of a cell to distinguish self from non self
B cell
Specific immune system response
Neutrophil
Engulfs foreign cells and displays a piece on cell membrane
Phagocytosis
Engulfing and destroy bacteria
Protiens made by B cells that mark pathogens to be destroyed
Antibodies
Antigen
Foreign cell
Helper T cell
Signals to B cells to make antibodies
Muetrpphils are part of
Nonspecific
B cell
Makes antibodies
Immune system is controlled by
White blood cells
Helper T cell
Signals to B cells to make antibodies
Vaccines stimulate body to produce
Antibodies
Antibodies
Protiems made by B cells that mark pathogens to be destroyed
When does a helper T cell become activated
When a macrophage displays an antigen
Macrophage
Phagocytosis
Cell engulfs foreign cell
Vaccines
Stimulate antibody production
when when same antigen comes back
More antibodies will be produced because the body remembers the antigen
Red blood cells
Deliver 02 using hemoglobin
White blood cells
Fight pathogens
Platelets
Clot blood
White blood cells have 2 parts
Neutrophils(nonspecific)(image immunity)
And
Lymphocytes( B cells and T cells)(specific)
Skin secretions reflexes
1st line of defense nonspecific
Neutrophil
White blood cells that use phagocytosis to engulf foreign cells (aka macrophages phagocytes)
Contain many lysosomes which are organelles that degrade pathogens
Epitope
Puts signal on cell telling immune system to kill it
Antigen
An epitope that is foreign foreign
3rd line of defense
Acquired immune response that counters specific invaders
Uses T cells B cells and antibodies
Helper T cells
Identify pathogen piece om outside of neutrophil and tells B cells which antibodies to make
Sees pathogen tells B cells which antibodies to make
B cells
Make antibodies
Killer T cells
Find pathogen with antibodies and kills it
Pathogen
T and B cells divide using
Mitosis
Antibody
Protiems made by B cells that attach to antigen so T cells knows fo kill if
Memory B cells
Remember antibody and make 100x more upon second infections
