What type of wound healing is characterized by the formation of granulation tissue?

The type of wound healing characterized by the formation of granulation tissue is secondary intention healing. In this process, wounds that cannot be approximated (brought together) heal through natural biological processes. Granulation tissue forms during this healing as the body works to repair the wound. This tissue is composed of new connective tissue and blood vessels, creating a foundation for the regeneration of skin and other tissues.

In secondary intention healing, the wound is allowed to close on its own, which typically takes longer and is more complex compared to primary intention healing, where edges are clean and can be easily stitched together. The presence of granulation tissue is crucial in secondary intention healing as it signifies that the body is actively working to fill in the wound and restore integrity. This process involves inflammation, tissue formation, and remodeling, which contrasts with other types of healing that do not necessarily involve the same degree of tissue regeneration.
