Tissue Response to Injury Flashcards
What are the 3 phases of the inflammatory response
- inflammatory response phase
- Fibroblastic repair phase
- Maturation-remodeling phase
about how many days is the inflammatory response phase?
3-4 days
about how long is the Fibroblastic repair stage?
about 6 weeks
about how long is the maturation-remodeling phase?
years or forever
Signs of inflammation
SHARP swelling heat altered function redness pallor (discoloration) or pain
when does healing begin?
immediately when the tissue is disrupted
what cells are part of the initial reaction and what is their role
phagocytes (clean up damaged cells) protect healthy cells localize damage to injured cells decrease injurious agents prepare for healing and repair
after about how long does clot formation begin and how long does it last?
after about 12 hours. lasts about 48 hours.
