Representing Immune Responce
Innate Immune Defence
Internal
Phagocytes
Capable of engulfing
and absorbing bacteria,
small cells and particles
Antimicrobial proteins
Can adhere to the
lipid membranes
of bacterial cells,
Antimicrobial resistance
Ant mechanism that enables
bacteria to
inhibit antimicrobial action
Peptide
A class of organic compounds consisting
of various numbers of amino acids
in which the amine of one is
reacted with the carboxylic
acid of the next to form anamide bond
Amphipathic
A molecule with both hydrophoic
and hydrophilic groups
that allow it to adhere to lipid
structures easily
Attack cells
Lymphocyte, able to bind
certain tumor cells and virus
infected cells, kill them by the
insertion or
granules containing perforation
Physical Barriers
External
Skin
Provides strong barrier
again diseases, only
get through if broken
Mucus membranes
Line entry openings of
human body
Nostril Hairs
Catch bacteria
Sweat
Sweat out pathogens,
fluid for exit
Oil
Protective film
Gastric fluids
Can break down cells of pathogens
Second Line
Innate immune response
Body recognises
invasion of bacteria or virus
Increase in white blood cells; phagocytes.
Phagocytes fight infection
Acquired Immune Responce
T Cells are active in the human body
White blood cells can recognise the antigen/pathogen - starts
regeneration process of cells
Helper T cells
Recognize the antigen/pathogen
B cells activate
B cells produce antibodies
Antibodies
destroy the antigen/pathogen
some antibodies can remainn and
protect against future pathogens
Killer T cells
Can work independant/direct to
destroy antigens/pathogens
