The video tutorial explains the wound healing process, which involves several overlapping phases. Initially, capillaries contract to reduce bleeding, and a clot forms. The inflammatory phase follows, with capillary dilation and white blood cell activity to eliminate dead tissue. During the proliferation phase, granulation tissue forms, supported by angiogenesis and fibroblast activity. Wound contraction and re-epithelialization occur next, leading to wound closure. Finally, the remodeling phase reorganizes collagen fibers to strengthen the scar tissue, a process that can last up to two years.
