**Question:**
At which letter is blood traveling TOWARDS the heart?

**Diagram Explanation:**
The diagram illustrates a simplified version of the human circulatory system, labeling various organs and indicating the direction of blood flow to and from the heart. At several points, labeled 'A', 'B', and 'C', blood flow is highlighted.

1. **Head**
2. **Lungs**
3. **Liver**
4. **Alimentary Canal**
5. **Kidneys**
6. **Legs**

- **Point A:** Blood flow at this point is labeled near the kidneys.
- **Point B:** Blood is labeled traveling to or from the liver.
- **Point C:** Blood flow at this point is connected to the lungs.

To determine the direction of blood flow towards the heart:
- Blood traveling **towards the heart** from the **lungs** (oxygenated blood) is likely illustrated near point 'C'.
- Blood traveling **towards the heart** from the **body organs** (deoxygenated blood) like the liver or kidneys, is seen near point 'B' or point 'A'.

Based on typical circulatory dynamics:
- At **C**, blood is traveling towards the heart from the lungs, which is a part of the pulmonary circulation where oxygenated blood returns to the heart.
   
Therefore, **C** is the label at which blood is traveling towards the heart.
