Explanation:
Following an injury to the skin, inflammation occurs, bringing platelets to form a blood clot, leukocytes to combat microbial invaders, and mesenchymal cells that develop into fibroblasts. Then the migratory phase begins, a scab is formed and epithelial cells migrate across the wound under the scab.
The relationship between the development of surface epithelium and the presence of a scab is that epithelium forms as the base of the scab.
The scab forms the outer layer that would be shed after the wound has been fully healed.
The epithelium, on the other hand, moves around the wound below the scab.
It also functions as the main barrier at mucosal surfaces and becomes the layer where the tissue is formed by closely aggregated cells.
Hence, in this case, it is concluded that scab and epithelium function to aid or repair a broken surface or a wound.
