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
-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
- 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
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
regulate behaviour of immune cells
complement system - ANSWER series of protons circulating in blood:
-facilitate phagocytosis of bacteria
-kill bacteria directly - form pores in bacterial cell membrane
function of complement system - ANSWER • Destruction of pathogens
• Opsonization of pathogens
• Recruitment of phagocytes
• Immune clearance
