व्याख्या :

Epithelial tissue plays a crucial role in wound healing. When the skin is wounded, epithelial cells at the edges of the wound multiply and migrate to cover the wound, forming a protective layer. This process is essential for the initial sealing of the wound and is one of the early stages in the overall wound healing process. Epithelial tissue helps in closing the wound and restoring the skin's integrity.
