Inferior Vena Cava: Anatomy and Function
The inferior vena cava (IVC) is the largest vein in the body. It returns deoxygenated blood from the lower extremities, pelvis, and abdomen to the right atrium.
Major Tributaries
- Common iliac veins (lower limbs, pelvis).
- Renal veins (kidneys).
- Hepatic veins (liver).
- Lumbar veins (posterior abdominal wall).
The IVC passes through the diaphragm at the caval opening (T8) and enters the right atrium. It is essential for systemic venous return.
