Wound healing refers to a living organism's replacement of destroyed or damaged tissue by newly produced tissue.
In undamaged skin, the epidermis (surface, epithelial layer) and dermis (deeper, connective layer) form a protective barrier against the external environment. When the barrier is broken, a regulated sequence of biochemical events is set into motion to repair the damage. This process is divided into predictable phases: blood clotting (hemostasis), inflammation, tissue growth (cell proliferation), and tissue remodeling (maturation and cell differentiation). Blood clotting may be considered to be part of the inflammation stage instead of a separate stage.
The wound-healing process is not only complex but fragile, and it is susceptible to interruption or failure leading to the formation of non-healing chronic wounds. Factors that contribute to non-healing chronic wounds are diabetes, venous or arterial disease, infection, and metabolic deficiencies of old age.
Wound care encourages and speeds wound healing via cleaning and protection from reinjury or infection. Depending on each patient's needs, it can range from the simplest first aid to entire nursing specialties such as wound, ostomy, and continence nursing and burn center care.
How this connects to Pathology
To study this topic responsibly, identify its normal structure or function, distinguish the main mechanism from its observable consequences, and ask which data can test a competing explanation. The subject foundations below outline these connections without pretending to be a specialist textbook chapter.

What the underlying subject studies
Pathology connects tissue and cellular changes to disease mechanisms. Begin with normal anatomy and physiology, describe what is disrupted, and distinguish an observed finding from its possible cause. A lesion pattern is often shared by several diseases.
How mechanisms and evidence connect
Organ injury may result from inflammation, ischemia, immune mechanisms, neoplasia, metabolic abnormalities or inherited conditions. The time course and host response influence morphology and clinical consequences.
How to develop a sound explanation
When studying a pathology topic, organize cause, mechanism, macro- and microscopic features, consequences and key differentials. Real diagnoses require clinical context, representative tissue and appropriate laboratory or imaging correlation.
