immune system - .....ANSWER ...✔✔ complex body
defines system- protects body against bacteria, viruses,
toxins and parasites
innate system - .....ANSWER ...✔✔ -present at birth
-not antigen specific
-present at all times
-does not improve with
repeated exposure to infectious agent
adaptive immune system - .....ANSWER ...✔✔ -
develops throughout life
-antigen specific
-lag time between infection and response
,2|Page
-memory develops- provides lifelong immunity to
reinfection
immune response - .....ANSWER ...✔✔ defend the life
of the individual - by identifying foreign substances in
body and developing defence against them
host response - .....ANSWER ...✔✔ The way that an
individual's body responds to an infection
leukocytes - .....ANSWER ...✔✔ -act like independent
single-cell organisms
-can move through tissues and capture micro-organisms
on their own
-2 types important in perio disease: PMNs,
Moncytes/macrophages
phagocytosis - .....ANSWER ...✔✔ process by which
leukocytes engulf and digest microorganisms
polymorphonuclear leukocytes - .....ANSWER ...✔✔
(PMNs)
-neutrophils
,3|Page
- rapid responders- 1st line of defence
- capture/ destroy bacterial invaders
-short-lived
what attracts leukocytes to an infection site -
.....ANSWER ...✔✔ PMNs are attracted to bacteria
by chemotaxis
lysosomes - .....ANSWER ...✔✔ strong bactericidal
and digestive enzymes in PMN
-perio pathogens are effectively destroyed by PMNs
monocytes/macrophages - .....ANSWER ...✔✔
monocytes:in the bloodstream
macrophages: in the tissues
-slower to arrive at infection site than PMNs
-surround/destroy bacteria
-long-lived cells in chronic inflammation
lymphocytes - .....ANSWER ...✔✔ small leukocytes-
help defend body
2 types: B cells, t cells
, 4|Page
B lymphocytes - .....ANSWER ...✔✔ B Cells
makes antibodies and pour into bloodstream
2 types: plasma/ memory b cells
antibodies - .....ANSWER ...✔✔ y shaped proteins
y binds w outside of b celll
-other end of y binds to a MO and kills it
antibodies - .....ANSWER ...✔✔ are known collectively
as immunoglobulins
T lymphocytes - .....ANSWER ...✔✔ T cells
intensify the response of other immune cells to bacterial
invasion
-produce CYTOKINES- further stimulate immune
response
cytokine - .....ANSWER ...✔✔ protein secreted by
cells and affects behaviour of nearby cells
