But that's not what you're proposing. An "organ system" is a collection
of tissues. You are proposing damage to a specific *tissue* in an organ
system, not to the organ system.

If you scratch your arm, you will see two things happen. The area
around the scratch will first turn whitish, and then it will turn red
and inflamed. Both of these are stages in a highly complex immune
response involving the release of histamines in the area of the wound.
Neither of these changes is particular to the damaged tissue itself,
but illustrates the complexity of the *organ system* that is the skin.

In answer to your question about what would happen to your burnt
tissues in a week, it would turn black and begin to smell very bad as
bacterial decomposition sets in. See "gangrene" and "frostbite" for
what happens to dead tissue as a function of time.
