What are the four stages of wound healing?

The correct sequence of the four stages of wound healing is recognized as Inflammation, Proliferation, Maturation, and Repair.

During the Inflammation stage, the body responds to injury with blood vessel dilation and increased permeability, allowing immune cells to reach the site and begin fighting infection. Following this, the Proliferation stage involves the formation of new tissue. This includes the synthesis of collagen and the regrowth of blood vessels, leading to the granulation phase where new tissue fills the wound. The third stage, Maturation, refers to the remodeling of the wound, where collagen is restructured for improved strength and function, enhancing the overall healing outcome.

The option identified does not align with the scientifically accepted stages of healing. While it includes the relevant phases, it's crucial to note that the healing process does not categorize stages as "Debridement" or "Repair" in the way suggested in that option. Instead, debridement may be a necessary procedure in the management of specific wounds within these stages, but it does not constitute a distinct stage of the healing process itself. Understanding these stages is essential in veterinary pharmacology as it informs the approaches to treatment and care for wounds in animals.
