PATHOLOGY

Detailed explanation-1: -Cutaneous wound healing is the process by which the skin repairs itself after damage. It is important in restoring normal function to the tissue.

Detailed explanation-2: -Repair after injury can occur by regeneration of cells or tissues that restores normal tissue structure, or by healing, which leads to the formation of a scar. In case of regeneration, the damaged or lost tissue is replaced by the proliferation of surrounding undamaged cells and tissue.

Detailed explanation-3: -Upon tissue injury, damaged cells release inflammatory chemical signals that evoke local vasodilation, the widening of the blood vessels. Increased blood flow results in apparent redness and heat.
