After pelvic lymph nodes, which lymph node group is next in the described drainage sequence?

Explanation:
Lymph drainage from the pelvis and lower body proceeds through regional lymph node groups in sequence. After the pelvic nodes, the next lymph node group is the lumbar (para-aortic) lymph nodes, which receive lymph from the pelvis and lower trunk before the fluid moves on to larger collecting structures. The cisterna chyli and thoracic duct are collecting/transport pathways, not lymph node groups, and the left venous angle is where the thoracic duct drains into the venous system. That’s why the lumbar lymph nodes are the correct next node group.
