What percentage of alcohol is passed through the small intestine into the bloodstream?

Approximately 80% of alcohol is absorbed into the bloodstream from the small intestine. After ingestion, alcohol passes through the stomach into the small intestine, where it is primarily absorbed into the bloodstream. The remaining percentage is typically absorbed by the stomach lining and metabolized by the liver. It's important to note that individual variations in factors such as metabolism and other physiological factors can influence the exact percentage of alcohol absorbed by the small intestine.
