How much alcohol is absorbed into the bloodstream from the stomach?

The absorption of alcohol into the bloodstream begins in the stomach, where approximately 20% of the alcohol consumed is absorbed. This process occurs relatively quickly and is influenced by various factors, such as the presence of food in the stomach, the concentration of alcohol in the beverage, and the rate at which the drink is consumed. Once absorbed, this alcohol enters the bloodstream and starts to affect the central nervous system, leading to the effects associated with intoxication.

The correct choice highlights that, while some alcohol can be absorbed in the stomach, the remaining approximately 80% will be absorbed later in the small intestine, where absorption rates are generally higher. Understanding this concept is crucial for servers and sellers, as it helps them gauge the potential effects of alcohol on customers based on how quickly they drink and whether they have eaten beforehand.
