 blood in the subclavian vein, where it undergoes an im- 

 mediate transformation. In this transformation tl.e

FIG. 88. Diagram showing the course of the main trunks of the absorb- 

 ent system : the lymphatics of lower extremities (D) meet the lacteals of 

 the intestines (LAC) at the receptaculum chyli (R.C.), where the thoracic duct 

 begins. The superficial vessels are shown in the diagram on the right arm 

 and leg (s), and the deeper ones on the left arm (D). The glands are here 

 and there shown in groups. The small right duct opens into the veins on 

 the right side. The thoracic duct opens into the union of the great veins of

 the food, prepared for absorption by the digestive process, 

 are taken up into the circulation under the different forms

 at certain times, in the blood; but these conditions are 

 temporary and transitional. The nutritive materials
