16 Lymphatics

Lymph Nodes of the Abdomen & Pelvis

Fig. 16.1   Lymphatic drainage of the internal organs
See Table 16.1 for numbering. Lymph drainage from the abdomen, pelvis, and lower limb ultimately passes through the lumbar lymph nodes (clinically: aortic nodes). The lumbar lymph nodes consist of the right (caval) and left lateral aortic nodes, the preaortic nodes, and the retroaortic nodes. Efferent lymph vessels from the lumbar and preaortic nodes form the lumbar and intestinal trunks, respectively. The lumbar and intestinal trunks terminate into the cisterna chyli.

Lymph Nodes of the Posterior Abdominal Wall

image Lymph nodes in the abdomen and pelvis may be classified as either parietal or visceral. The majority of the parietal lymph nodes are located on the posterior abdominal wall.
