This chyle isthe part of the food which absorbsinto the lacteals, one of which runsin the center of each villus. Theselacteals run into larger trunks, whichfinally enter the thoracic duct. In structure walls of the lym-phatic vessels are composed of anendothelium, a muscular layer, and aconnective tissue layer. The flow of the lymph in thesevessels is due to the pressure in thetissues, where, as described, there isa constant overflow of lymph. Lymphatic nodes. In the course ofthe lymphatics are numerous struc-tures known as hjmpli nodes or lymphgla
