Site of injury
Healing of a wound. (
) If normal skin is (
) injured, (
) blood escapes from dermal blood vessels, and (
) a blood clot soon forms.
) The blood clot and dried tissue F
uid form a scab that protects the damaged region. (
) Later, blood vessels send out branches, and ±
migrate into the area. The ±
broblasts produce new connective tissue ±
bers, and (
)when the skin is mostly repaired, the scab sloughs o²
. Scar tissue
continues to form, elevating the epidermal surface.
