wall, and the left forelimb. The thoracic duct receives the 

 lymph from the lungs, heart, all the abdominal viscera, and 

 muscles, and the hind-limbs. With but few exceptions, all 



the main lymphatic vessels pass 

 through lymphatic glands before 

 reaching one of the three main 

 trunks. In fact, the vessels bring- 

 ing the lymph to the glands may 

 be said to terminate there. They 

 are called afferent lymphatics. 

 The lymph moves free through 

 the tissue of the gland, and on 

 the opposite side is taken up by 

 the efferent lymphatics. 



The right and left tracheal 

 trunks lie on their respective sides 

 of the trachea and empty into 

 the external jugular vein just be-
