Absorption
Alcohol is absorbed from all parts of the gastrointestinal tract largely by simple diffusion into the blood. However the small intestine is by far the most efficient region of the gastrointestinal tract for alcohol absorption because of its very large surface area. In a fasting individual, it is generally agreed that 10% to 20% of a dose of alcohol is absorbed from the stomach (the volume of alcohol affects the absorption) and 75% to 80% is absorbed from the small

Alcohol Content
It 's not how many drinks that you have, but how much alcohol that you consume. The concentration of the drinks that one ingest can have a slight effect on the peak alcohol concentration due to the differences in absorption rate of different concentrations of alcohol. Alcohol is most rapidly absorbed when the concentration of the drink is between 10% and 30%. Below 10% the concentration gradient in the gastrointestinal tract is low and slows absorption and the added volumes of liquid involved slow gastric emptying. On the other hand concentrations higher than 30% tend to irritate the mucous membranes of the gastrointestinal tract and the pyloric sphincter, causing increased secretion of mucous and delayed gastric emptying.
Food
Food taken along with alcohol results in a lower, delayed blood alcohol concentration peak (the point of greatest intoxication). There are two major factors involved in this phenomenon.
First, because alcohol is absorbed most efficiently in the small intestine, the ingestion of food can slow down the absorption of alcohol into one 's system. The pyloric valve at the bottom of the stomach will close in order to hold food in the stomach for digestion and thus keep the alcohol from reaching the small intestine.
