complex body defines system- protects body
immune system
against bacteria, viruses, toxins and parasites
-present at birth

-develops throughout life
-antigen specific
adaptive immune system -lag time between infection and response
-memory develops- provides lifelong immunity to
reinfection
defend the life of the individual - by identifying
immune response foreign substances in body and developing defence
against them
The way that an individual's body responds to an
host response
infection
-act like independent single-cell organisms
-can move through tissues and capture micro-
leukocytes organisms on their own
-2 types important in perio disease: PMNs,
Moncytes/macrophages
process by which leukocytes engulf and digest
phagocytosis
microorganisms
(PMNs)
-neutrophils
polymorphonuclear
- rapid responders- 1st line of defence
leukocytes
- capture/ destroy bacterial invaders
-short-lived
what attracts leukocytes PMNs are attracted to bacteria by chemotaxis
to an infection site
strong bactericidal and digestive enzymes in PMN
lysosomes -perio pathogens are effectively destroyed by
PMNs
monocytes:in the bloodstream
macrophages: in the tissues
monocytes/macrophages -slower to arrive at infection site than PMNs
-surround/destroy bacteria
-long-lived cells in chronic inflammation
small leukocytes- help defend body
lymphocytes
2 types: B cells, t cells

B Cells
makes antibodies and pour into bloodstream
B lymphocytes
2 types: plasma/ memory b cells
y shaped proteins
y binds w outside of b celll
antibodies
-other end of y binds to a MO and kills it
antibodies are known collectively as immunoglobulins
T cells
intensify the response of other immune cells to
bacterial invasion
T lymphocytes
-produce CYTOKINES- further stimulate immune
response
protein secreted by cells and affects behaviour of
cytokine nearby cells
regulate behaviour of immune cells
series of protons circulating in blood:
-facilitate phagocytosis of bacteria
complement system
-kill bacteria directly - form pores in bacterial cell
membrane
• Destruction of pathogens
function of complement • Opsonization of pathogens
system • Recruitment of phagocytes
• Immune clearance
trans-endothelial leukocytes push their way between endothelial cells
migration and enter connective tissue
leukocytes travel through the bloodstream to fight
migration
an infection
body response to focuses host defence components at the site of an
inflammation infection to eliminate MOs and heal damaged tissue
inflammatory Biologically active compounds secreted by cells-
biochemical mediators activate the body's inflammatory response
