As you pick yourself up, you notice that your knee is bleeding. But while you're trying to figure out where that rock came from, the blood from the cut on your knee is already busy at work creating a scab.

As soon as you scrape or break the skin anywhere on your body, special blood cells called platelets (say: playt-lits) spring into action. Platelets stick together like glue at the cut, forming a clot. This clot is like a protective bandage over your cut that keeps more blood and other fluids from flowing out. The clot is also full of other blood cells and thread-like stuff called fibrin (say: fy-brin) that help hold the clot together.

So you cleaned up but in the body up to the scab thoso cells are working for build the skin again As the clot starts to get hard and dries out, a scab forms. Scabs are usually crusty and dark red or brown. Their job is to protect the cut by keeping germs and other stuff out and giving the skin cells underneath a chance to heal.

If you look at a scab, it probably just looks like a hard, reddish glob. But under its surface, all kinds of things are going on. New skin cells are being made to help repair the torn skin. Damaged blood vessels are being fixed.
