The document discusses the different phases of wound healing: 1) Bleeding phase occurs immediately after injury and lasts 6-8 hours. 2) Inflammation phase begins within 6-8 hours and reaches peak reaction between 1-3 days to stop bleeding and begin clotting. 3) Proliferation phase lasts 2-3 weeks as collagen is produced to form scar tissue through granulation, contraction, and re-epithelialization. 4) Remodeling phase results in regaining strength over time but risk of breakdown remains high as structure and density are reorganized.
