How does the body handle ethanol?

• A. Absorption, Distribution, Elimination
• B. Digestion, Absorption, Excretion
• C. Elimination, Absorption, Distribution
• D. Absorption, Elimination, Distribution

Answer: (C)

Ethanol is handled by the body through three connected processes: absorption into the bloodstream, distribution through body water, and elimination mainly by liver metabolism. After you ingest alcohol, it is absorbed relatively quickly from the stomach and small intestine, then it disperses throughout the body's water compartments (distribution). The crucial part for clearing alcohol is elimination, which occurs primarily in the liver as ethanol is metabolized to acetaldehyde and then to acetate and eventually excreted. The rate at which elimination happens largely governs how quickly blood alcohol concentration falls over time, making it the defining step in how the body clears ethanol. So, while absorption and distribution describe how ethanol enters and spreads in the body, elimination is the key process that removes it from the system, which is why this framing is emphasized in the context of how the body handles ethanol. The other sequences don’t reflect the actual flow as accurately—ethanol must be absorbed before it can be eliminated, and it distributes as it circulates.
