Description: (Location & Drainage)
The internal iliac lymph vessels are situated along the internal iliac artery. The vessels drain lymph from the parietal lymph nodes of the internal iliac region, the superior gluteal, inferior gluteal and sacral lymph nodes. In addition, the internal iliac lymph vessels drain lymph from the visceral internal iliac lymph nodes, such as the paravesical, parauterine, paravaginal, and pararectal lymph nodes. The internal iliac lymph vessels transmit lymph from the aforementioned nodes to the common iliac lymph nodes, which subsequently drain into the lateral aortic and caval lymph nodes, and then to the lumbar trunks and the cisterna chyli.

Lymph Vessel
The lymph vessels are blind-ending capillaries which have gaps in their endothelial walls enabling protein molecules to move through easily.
