Three phases of alcohol in the body are?

• A. Absorption, Distribution, Elimination
• B. Absorption, Metabolism, Elimination
• C. Ingestion, Diffusion, Elimination
• D. Absorption, Distribution, Excretion

Answer: (A)

The concept being tested is how alcohol is processed in the body in three stages: absorption, distribution, and elimination. Alcohol is absorbed from the stomach and small intestine into the bloodstream. It then distributes quickly to tissues with high blood flow, including the brain, which is why intoxication effects are felt early. Elimination is the final phase, dominated by liver metabolism, with a smaller amount exiting unchanged via breath, urine, and sweat. This framework—absorption, distribution, elimination—best captures how the body handles alcohol, because metabolism and excretion are grouped under elimination in this context. Choices that include ingestion or diffusion describe nonstandard steps, and treating metabolism as a separate phase or using excretion instead of elimination doesn’t align with the typical three-phase model used here.
