Question: 1 / 400

What type of tissue forms during the healing of a skin injury that cannot be surgically closed?

Skeletal tissue

Granulation tissue

Granulation tissue is a crucial component in the healing process of a skin injury that cannot be surgically closed. This type of tissue forms during the proliferation phase of wound healing and is made up of new connective tissue and tiny blood vessels. It provides a scaffold for cell migration and is essential for the repair of damage. Granulation tissue appears as red, bumpy tissue and serves to fill in the wound area, ultimately bridging the gap as healing progresses.

The formation of granulation tissue indicates the body’s natural response to injury, promoting healing through inflammation and the recruitment of cells necessary for tissue repair. It plays a significant role in preventing infection and facilitating the growth of new epithelial tissue over the wound. Over time, granulation tissue is remodeled and may eventually be replaced by scar tissue, but its initial formation is critical for effective healing of open wounds.
