Final answer:
Alcohol diffuses through the stomach wall into the bloodstream. Food delays absorption and stomach emptying, while vomiting can protect against a high dose of toxin. Alcohol is rapidly absorbed in the small intestine, regardless of food intake.
Step-by-step explanation:
Alcohol diffuses through the stomach wall into the bloodstream. While water, salt, and simple sugars can be absorbed into the blood from the stomach, most other substances are broken down in the small intestine before they are absorbed. The stomach stores food until the small intestine is ready to receive it, and a circular muscle controls the opening between the stomach and small intestine. When the small intestine is empty, the muscle relaxes and allows food to pass from the stomach into the small intestine.
Food delays absorption and stomach emptying, which means that alcohol is absorbed more slowly when consumed with food. Vomiting can protect against a high dose of toxin by expelling the substance from the body. However, it's important to note that inducing vomiting is not a safe or effective method to eliminate alcohol from the body.
Alcohol is rapidly absorbed in the small intestine, regardless of whether it is consumed with or without food. The small intestine has a large surface area that allows for efficient absorption of alcohol into the bloodstream.
