Wound Healing

When tissue injury occurs, the body initiates a complex wound healing process that unfolds in distinct phases. Initially, an inflammatory response activates as the first line of defense to manage the injury.

Wound Healing

Phase III: Remodeling and Maturation

Occurs several weeks after injury.

Assembly and remodeling of the cellular matrix
Process can be delayed by certain medications including steroids and NSAIDS

Systemic Response

Natural Barriers

First Line of Defense

Inflammatory Process: Phase I

Reconstruction: Phase II

Proliferation and new tissue growth 3-4 days post Injury
Granulation tissue growth MMPs breakdown extracellular matrix proteins
Angiogenesis factors

stimulate vascular endothelial buds growing into wound

Fibroblasts stimulated by transforming growth factor-beta

Wound Healing

Second line of defense

Rapid Response
Subtopic
