Quote: “does alcohol taken in through drinking end up in the intestines?”
Anything you swallow goes into your stomach; from there it travels into your intestines where the substances that are needed for survival are absorbed. Some of the liquid we take in is used in the formation of waste and continues into the colon, through the rectum and is finally eliminated. Liquid that's not used during stool or waste formation ends up in the bloodstream and is eventually filtered through the kidneys, bladder, and out of the body.
