The image displays a diagram of the human lymphatic system alongside the vascular system. The major components are labeled with numbers. Here's a detailed transcription and explanation suitable for an educational website:

### Labeled Diagram of the Human Lymphatic System

1. **Cervical Lymph Nodes**: Located in the neck, these nodes filter lymphatic fluid and trap pathogens.
2. **Jugular Veins**: Major veins in the neck that drain blood from the head.
3. **Subclavian Veins**: Veins that receive lymph from the lymphatic vessels and drain blood from the arms.
4. **Thoracic Duct**: The largest lymphatic vessel in the body, it drains lymph into the circulatory system.
5. **Left Bronchomediastinal Trunk**: Collects lymph from the thoracic organs.
6. **Spleen**: An organ involved in blood filtration and immune response.
7. **Mesenteric Lymph Nodes**: Located in the abdominal region, these nodes filter lymph from the intestines.
8. **Inguinal Lymph Nodes**: Found in the groin, responsible for filtering lymph from the lower limbs and abdomen.

### Accompanying Diagram

- **Color-Coded Drainage System**:
   - The left side of the body is shown to be drained by the *thoracic duct* (labeled 9).
   - The right side is drained by the *right lymphatic duct* (labeled 10).

### Compass

- At the bottom right, a compass indicates the orientation with:
  - **S**: Superior (upwards)
  - **R**: Right (the figure’s right side)
  - **L**: Left (the figure’s left side)

This diagram is helpful for understanding the pathways through which lymph circulates and is filtered through the lymphatic system, along with its relationship to the vascular system.
