Questions and Answers

What triggers inflammation?

  • Bacterial infection only
  • Allergens
  • Infection, tissue damage, or harmful substances (correct)
  • Viral infection only
  • What is the role of mast cells in inflammatory responses?

  • Produce collagen for wound healing
  • Release histamine, leading to vasodilation and increased permeability (correct)
  • Coordinate the release of cytokines
  • Engulf and digest pathogens
  • What happens during the proliferation phase of wound healing?

  • Fibroblasts produce collagen and angiogenesis occurs (correct)
  • Vasodilation and increased permeability
  • Inflammatory cells clear debris and pathogens from the wound
  • Resolution of the inflammatory response
