Answer
The inferior vena cava (IVC) is a major vein that collects deoxygenated blood from various parts of the body and carries it back to the right atrium of the heart. The abdominal tributaries are smaller veins that drain into the IVC. The ones you mentioned are:
1. **Lumbar Veins:** These veins drain blood from the lower back muscles and structures and contribute to the IVC's venous drainage.
2. **Gonadal Veins (Ovarian or Testicular):** In females, the ovarian veins drain blood from the ovaries, while in males, the testicular veins drain blood from the testes. These veins play a role in the venous drainage of the reproductive organs.
3. **Renal Veins:** The renal veins drain blood from the kidneys. They carry the filtered and deoxygenated blood from the kidneys back to the IVC.
4. **Suprarenal Veins:** These veins drain blood from the adrenal glands, which are located on top of each kidney. They contribute to the IVC's venous drainage.
5. **Hepatic Veins:** The hepatic veins drain blood from the liver. They collect the blood that has been filtered through the liver and return it to the IVC.
6. **Inferior Phrenic Veins:** These veins drain blood from the inferior surface of the diaphragm, the muscle that separates the thoracic and abdominal cavities.
These abdominal tributaries play a crucial role in returning deoxygenated blood from various abdominal organs and structures to the IVC, which then carries it to the heart for reoxygenation. For more specific details, especially from the table you mentioned, I recommend consulting an anatomy textbook or medical resource.
