Superior mesenteric- drain nodes in the mesentery Preaortic nodes: lie in front of the aorta near the vessels of the nameĬoeliac- drain gastric, hepatic and pancreaticosplenic node They lie in front of the lumbar vertebral bodies near the aorta and are in three groups: preaortic, paraaortic and retroaortic It drains into the junction of the right internal jugular and right subclavian veins or each of these veins separately. Right lymphatic duct- It drains right head, neck, right arm (via right jugular trunk), right thorax (via right subclavian trunk) and right upper abdomen to umbilicus (via right Brachiocephalic trunk). It terminates either into the junction of the left internal jugular and subclavian veins or one of those veins.
It drains lymph from the left arm (via left subclavian), left neck and head (left jugular, left thorax, left upper abdomen (to umbilicus), both sides of the abdomen below the umbilicus and both lower limbs. It begins as either a plexus by the confluence of several lymphatics on the posterior abdominal wall or a dilatation termed the cisterna chyli. Thoracic duct- this is the largest lymphatic channel in the body extending from L1 to the root of the neck. Intestinal lacteals help in the absorption of fat and protein from food (this gives lymph fluid the rich milky colour).Most of the lymphocytes are formed in the lymph glands.Lymph nodes perform a filtering function by removing harmful substances (bacteria, virus etc) from the interstitial fluid.An amount of this interstitial fluid is drained by the lymphatic system. Interstitial fluid derived from blood bathes the cells and provides oxygen and nutrients to the cells and then most of the fluid passes back into the bloodstream carrying carbon dioxide and waste products.
