How is alcohol typically absorbed into the bloodstream?

Alcohol is primarily absorbed into the bloodstream through the stomach and small intestine. When a person consumes alcohol, it enters the stomach, where a portion is absorbed directly into the bloodstream. However, the majority of absorption occurs in the small intestine due to its large surface area and the presence of specialized cells that facilitate the absorption of nutrients, including alcohol. Once absorbed, alcohol quickly enters the bloodstream and is distributed throughout the body.

The lungs, large intestine, and direct injection are not typical pathways for alcohol absorption. While some substances can be absorbed through the lungs, such as certain gases or vapors, this method is not relevant for alcohol in its common consumption form. The large intestine's primary function is to absorb water and electrolytes, not to absorb alcohol efficiently. Direct injection is not a common or safe method of alcohol consumption and is not how alcohol is typically absorbed into the bloodstream.
