I am discussing this topic because it was one of many the questions on the first Human Anatomy and Physiology exam. Due to the limited time, I couldn't provide a correct answer to the question, and it stuck in my head. I decided to explain it here.
During inflammation, blood vessels dilate and become more permeable causing, tissues to become red and swollen. The body is responds to the injuryin various ways. A superficial cut is simply filled by reproducing epithelia cells. In contract, deeper cuts are first closed off by clots, and then covered by scabs and filled in by fibroblasts making connective tissue. Blood vessels extend into the wound, it rplaced and the scab falls off. Larger wounds leave scars and require longer of healing times.
