Answer

To solve the question, "Lymph collected from the left side of the body collected through the thoracic duct and finally opens into," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Lymphatic System**:
- The lymphatic system is responsible for collecting excess tissue fluid (lymph) from the body and returning it to the bloodstream. Lymph is formed from the extracellular fluid that surrounds cells.

2. **Thoracic Duct Function**:
- The thoracic duct is the largest lymphatic vessel in the body. It collects lymph from the left side of the body, including the left arm, left side of the head, neck, and the lower body.

3. **Pathway of Lymph**:
- The lymph collected by the thoracic duct is transported towards the upper body.

4. **Opening of Thoracic Duct**:
- The thoracic duct empties its contents into the venous system. Specifically, it opens into the left subclavian vein, which is located near the heart.

5. **Conclusion**:
- Therefore, the lymph collected from the left side of the body through the thoracic duct finally opens into the left subclavian vein.

### Final Answer:
The lymph collected from the left side of the body through the thoracic duct finally opens into the **left subclavian vein**.
