TCDHA PERIO 1 FINAL EXAM LATEST 2025-2026
UPDATE QUESTIONS AND ANSWERS
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
