What kills you when you burn to death?

Ok so the title sounds a bit silly but my question is,

What exactly is shutting down or ceasing to function when one burns to death? Obviously burning skin probably wouldn't *kill* you (not quickly anyway) and pain cant kill people AFAIK

So what is the fire doing to your body that causes you to die? is it heatstroke? does the fire burn through your skin and begin directly damaging organs? i was of the understanding fire killed you long before it was able to do this.

If your skin is burned deeply enough and widely enough, it can compromise circulation and also breathing as the skin tightens and blood vessels are compressed and the chest is unable to expand. In such circumstances an escharotomy can be performed, putting long incisions in the burned skin to allow the chest to expand without the skin needing to stretch.

It's very not pretty, in case you were thinking of googling it.
