What is the white area of my elbow? (photo)

I've recently fell, while running to school and scraped the already formed scab off of my elbow. It has formed this white, smooth, and soft wound after three days of wet bandages. The edges of the wound seem to start pulling together, but it just looks weird and fascinating. I would like to know what is happening to my elbow, and does this happen with every wound of this type. Thanks for the help!
