Explanation:
Detailed explanation-1: -Special blood cells called platelets form a clot at the injury. These cells act like a bandage to stop bleeding and keep out germs and debris. As the clot dries, it forms a scab.
Detailed explanation-2: -The scab is there to protect the wound and forms after your blood has clotted and the surface of the wound starts to dry out. It might look red or brown, and covers the wound as healing continues underneath the scab. A scab is there to help prevent infection by keeping out bacteria.
