The capillaries of the villus are connected with the veins which contribute 

 to the portal vein, hence carry blood to the liver. The lacteals of the villus 

 contribute to the mesenteric lacteal system, hence the chyle and lymph pass 

 through the mesenteric glands and the thoracic duct to the subclavian vein

 left mamma detached and thrown outward over the left arm, so as to expose a great part 

 of its deep surface. The principal lymphatic vessels and glands are shown on the side 

 of the head and face, and in the neck, axilla, and mediastinum. Between the left internal 

 jugular vein and the common carotid artery, the upper ascending part of the thoracic duct 

 marked i, and above this, and descending to 2, the arch and last part of the duct. The
