Model of the LymphaticSystem in the HumanBody

The most important function of the lym-phatic system in the human body is thedrainage and removal of tissue fluid fromorgans and tissues. The lymph vessels startas very fine blind sacs (cul de sacs) in the in-terstitial tissue. Larger lymph vessels areformed when several of these small vesselsjoin, and the former then generally run pa-rallel to the veins. Lymph nodes occur allover the lymphatic pathways. These filterand control the lymph. Germs can also becaught in the lymph nodes and renderedharmless. The lymphatic system is there-fore an important component in the de-fence system (immune system). Sincegerms, particularly cancer cells, are general-ly transported along the lymphatic path-ways, the location of lymph nodes, whichare always part of a region (so-called regi-onal lymph nodes) is of special signifi-cance. The model shows the most impor-tant regional lymph nodes in the head,

neck, skin and limbs. The large vessels tra-velling towards the liver (hepatic artery,portal vein, etc.) and their lymph vesselsand nodes can be removed so that the cis-terna chyli, which lies in the diaphragmslot, and the starting section of the thora-cic duct (ductus thoradcus) can be exposed.

The lymphs in the two lower limbs, in thepelvic and stomach area and those in theleft side of the head, left'side of the neck,left arm and the majority of the chest cavitywith the organs contained therein, flowinto the thoracic duct (ductus thoradcus),which empties into the left venous angle(joining of internal jugular vein and the suhc-lavian vein). The lymphs on the right sideof the body, in the right arm and a sectionof the (chiefly) right side of the thoraciccavity, join in the right lymphatic duct(ductus lympbaticus dexter), which emptiesinto the right venous angle. The lymph fi-nally flows back over the superior venacava and into the circulation system.
