Eli5: what specific parts in the body define alcohol tolerance?

381 viewsBiologyOther

I wonder what defines alcohol tolerance in the biological level. Like because of this part or trait, I can drink x amount of bottles compared to the other guy that can only drink y amount od bottles.

Its said that you can develop alcohol tolerance, so I wonder which parts of the body change to reflect that.

The only trait that I know of currently is the size of the body since technically given the same amount of alcohol, a smaller body will be filled up more compared to a larger body.

I am a 135 lb dude. I no longer drink, but went from having very little tolerance (a beer would get me buzzed) to working in a bar, drinking every day, and having a much higher tolerance. I gained no weight. It for sure has to do with whatever organs process alcohol. When they are forced to do it alot, they build up whatever enzymes or hormones do that. And if they dont have to break down alcohol that often, prune back whatever processes that were being used before.
