Answer:
Step-by-step explanation:
When your body's skin cells are constantly regenerating and replacing the older skin cells that make up the most superficial layer of your skin. This helps to explain why, when you experience a minor injury to the outermost layer of skin, or epidermis, the healing process takes places so rapidly. When you get a shallow cut or scrape, the cells around the perimeter of the wound literally "divide and conquer." First, they split off from adjacent cells and begin to divide and multiply, while the epidermal cells now left along the outer edge of the wound do the same. As the cells multiply, they begin to travel across the wound, converging with other cells. For most small wounds, after several days a bridge of new skin cells will have formed over the wound; however, this process may take slightly longer for broader wounds.
