Quick Facts
Location: Accompanies the inferior epigastric artery.
Drainage: Umbilical region and rectus abdominis muscle.
Direction of Flow: External iliac nodes > Common iliac lymph nodes > Lateral aortic lymph nodes (left) and lateral caval lymph nodes (right) > left and right lumbar lymph trunk > cisterna chyli > thoracic duct.
Description:
Description: (Location & Drainage)
The inferior epigastric nodes belong to the parietal abdominal lymph nodes. The left and right lumbar and inferior diaphragmatic nodes make up the remainder of this group.
The inferior epigastric nodes form clusters of three to six nodes adjacent to the inferior epigastric arteries (Földi et al., 2012). Their afferent vessels receive lymph from the umbilical region and the rectus abdominis muscle, while their efferent vessels drain into the external iliac nodes, more specifically the lowest nodes of the external iliac nodal group known as the lacunar nodes (Földi et al., 2012).

Lymph Node
Lymph nodes are a part of the lymphatic system, which also includes lymphatic vessels that collect interstitial fluid or lymph (including invaded microbes in case of infections) from all vascularized tissues and discharge it into their draining lymph nodes.
