AND ANSWERS 2026/2027 100%
CORRECT
What is the effect of histamine in inflammation? - ANSWER>Triggers vasodilation and increases capillary
permeability.
What is the result of vasodilation and increased capillary permeability? - ANSWER>Increased blood flow and
increased movement of proteins and cells to injured tissue.
What are the four symptoms of inflammation induced by histamine? - ANSWER>Redness, swelling, heat, and pain.
What is the third event in inflammation? - ANSWER>Containment of foreign matter.
What do mast cells and basophils release during containment? - ANSWER>Mast cells and basophils release the
anticoagulant, heparin.
, What is the effect of heparin in early inflammation? - ANSWER>Prevents clot formation initially so blood cells can
access area.
What happens after initial prevention of clotting? - ANSWER>Clotting factors eventually form a clot around clusters
of bacteria, which prevents their spread.
What happens to the clot at the skin's surface? - ANSWER>At the skin's surface dries and hardens (scab).
What happens to the scab during healing? - ANSWER>Replaced with new cells as wound healing takes place.
What is the fourth event in inflammation? - ANSWER>Leukocyte proliferation and migration.
What happens during leukocyte proliferation? - ANSWER>Cytokines travel to bone marrow.
What do cytokines do in the bone marrow during inflammation? - ANSWER>Stimulate production of leukocytes.
What is the result of increased leukocyte production? - ANSWER>Increase 4 to 5 times in circulating numbers
(leukocytosis).
