Answer 2

If you are speaking about the immediate reaction of skin redness after slapping your arm: that is due to the release of histamine - which dilates blood vessels under the skin and gives you that red color.

If you are talking about bruises, that is a different (cooler) process. Bruises are made when there is trauma to a blood vessel which allows blood to leak out of vessels and into skin tissue.
