Answer

**Step-by-Step Solution:**

1. **Understanding Alcohol Absorption**: Recognize that alcohol is absorbed primarily in the digestive system after consumption.

2. **Identifying Key Locations**: The main sites for alcohol absorption are the stomach and the small intestine.

3. **Absorption Rates**: Approximately 80% of alcohol is absorbed in the stomach, while the remaining 20% is absorbed in the small intestine.

4. **Role of Villi**: The absorption process is facilitated by the presence of villi, which are tiny, finger-like projections in the lining of the stomach and small intestine that increase the surface area for absorption.

5. **Metabolism Location**: Although absorption occurs in the stomach and small intestine, the metabolism of alcohol takes place in the liver.

6. **Evaluating Options**:
- Mouth: Incorrect, as minimal absorption occurs here.
- Mouth and esophagus: Incorrect for the same reason.
- Stomach and small intestine: Correct, as this is where the majority of absorption occurs.
- Throughout the alimentary canal: Incorrect, since absorption is not uniform throughout.

7. **Conclusion**: The correct answer is that alcohol is absorbed in the stomach and small intestine.

**Final Answer**: Stomach and small intestine.
