**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the location of the vomiting center in the human body.

2. **Definition of the Vomiting Center**: The vomiting center is a neural structure responsible for coordinating the vomiting reflex. It processes various signals from the body that trigger the act of vomiting.

3. **Identifying Possible Locations**: The options provided are:
- Medulla oblongata
- Stomach and sometimes in duodenum
- GI tract
- Hypothalamus

4. **Analyzing Each Option**:
- **Medulla Oblongata**: This is a part of the brainstem that controls various involuntary functions, including the vomiting reflex. It is known to contain the vomiting center.
- **Stomach and Duodenum**: While these organs can be involved in the process of vomiting (emesis), they do not contain the vomiting center itself.
- **GI Tract**: Similar to the stomach and duodenum, the gastrointestinal tract can react to vomiting signals but is not the site of the vomiting center.
- **Hypothalamus**: This part of the brain regulates various autonomic functions, including temperature control, but is not involved in the vomiting reflex.

5. **Conclusion**: Based on the analysis, the correct answer is that the vomiting center is located in the **medulla oblongata**.

**Final Answer**: The vomiting center is located in the **medulla oblongata**.
