PATHOLOGY

Detailed explanation-1: -Epithelialization is defined as a process of covering denuded epithelial surface. The cellular and molecular processes involved in initiation, maintenance, and completion of epithelialization are essential for successful wound closure.

Detailed explanation-2: -Hemostasis Hemostasis is the first stage in wound healing that can last for two days. As soon as there is a wound on the body, the blood vessels in the wound area constrict to reduce the blood flow. This is known as vasoconstriction.

Detailed explanation-3: -The epidermis is the first, or most superficial, layer of skin. A first-degree abrasion is considered mild. It won’t bleed. First-degree abrasions are sometimes called scrapes or grazes.

Detailed explanation-4: -Epithelial tissue (Figure 3.12) is formed in the final stages of healing. This tissue forms the new epidermis. Epithelial tissue is superficial pink/ white tissue that migrates across the wound from the wound margin, hair follicles or sweat glands. It will cover the granulating tissue.
