Hemostasis: Immediate response to stop bleeding through clot formation. Inflammation: Clears the debris and prepares the wound for new tissue formation. Proliferation: Involves re-epithelialization, angiogenesis, and fibroplasia. Remodeling: Maturation and reorganization of the newly formed tissue.
Histologically, these stages can be observed as sequential changes in cell types and extracellular matrix components.
