lumbar lymph nodes

Lumbar lymph nodes refer to a group of small organs that are part of the immune system. Lymph nodes are generally circular protuberances that are dispersed throughout the body. The lumbar lymph nodes are located in the region of the body between the diaphragm and pelvis known as the lumbar. They are also called the lateral aortic nodes. The nodes are part of the lymphatic system of the human body. They are situated alongside a vein in the torso known as the inferior vena cava and an artery known as the aorta. The common iliac nodes and lymphatic vessels found on the backside of the abdominal wall enter into the lumbar nodes. The nodes also provide lymphatic vessel extensions that form lumbar trunks on both sides. The left lumbar trunk of the nodes receives drainage from the intestinal trunk. The lumbar trunks converge to become the thoracic duct. The lumbar lymph nodes are responsible for draining body parts such as the lower limb, pelvic organs, the perineum, and the abdominal wall among others.
