To answer the question "Which part of the brain controls the heart?", we can break down the information step by step:

### Step-by-Step Solution:

1. **Understanding Brain Structure**: The brain is divided into three main parts: the forebrain, midbrain, and hindbrain.

2. **Focusing on the Hindbrain**: Among these, the hindbrain is particularly important for controlling various autonomic functions.

3. **Components of the Hindbrain**: The hindbrain consists of three main structures: the cerebellum, pons, and medulla oblongata.

4. **Identifying the Key Structure**: The medulla oblongata, often referred to simply as the medulla, is a crucial part of the hindbrain.

5. **Functions of the Medulla**: The medulla contains centers that control vital functions, including respiration and cardiovascular reflexes.

6. **Control of Heart Rate**: Specifically, the medulla is responsible for regulating the heart rate and other cardiovascular functions.

7. **Conclusion**: Therefore, the part of the brain that controls the heart is the **medulla oblongata**.

### Final Answer:
