The Lymphatic System 91 may be. seen by ocdinary dissection, the structures which appear in this way in being the , or lymph nodes, centres of cell formation, occuring in the course of the conducting vessels. These as superficial structures are found either singly, as in the head and neck, or more or less grouped, as in the axillary and inguinal spaces. As deep structures they are conspicuous in the intestinal mesen- teries, and in the walls of the digestive tube, occuring in the latter chiefly as continuous masses of lymph, follicles, as, for example, in the walls of the sacculus rotundus, the vermiform process, or the tonsil; or, again, as aggregated lymph follicles (Peyer's patches) at various points in the intestinal wall. The conducting portion of the system comprises an extensive series of canals, beginning as phatic capillaries in peripheral organs, and ending as lymphatic trunks which empty into the great veins. The lymphatic trunks of the anterior portion of the body are designated from their association with the corresponding veins as jugular and subclavian. They enter the venous system on either side at the point of junction of the internal and external jugular veins or of the common jugular and sub- clavian (Fig. 82). The lymphatic vessels of the posterior portion of the body, including the intestine, unite to form a common canal, the thoracic duct. The latter lies for the most part between the aorta and the vertebral column, and traverses the thorax in this position to enter, the venous system at the same point as the jugular and subclavian trunks of the left side. The lymphatic capillaries are terminal, absorptive vessels, differing from blood capillaries both in ,racter of their walls and in their relations to other portions of the system, siiice they are-wot interposed as in the vascular systein between
