EXPLANATION OF PLATE III. 



A GENERAL VIEW OF THE LYMPHATIC OR ABSORBENT SYSTEM 

 OF VESSELS. 



At e is seen a portion of the small intestine from which lacteals or 

 chyle-conveying vessels, d, proceed ; at f the thoracic duct, into which 

 the lacteals open. This duct passes up the back of the chest, and 

 opens into the great vein at g, on the left side of the neck : here the 

 chyle mingles with the venous blood. In the right upper and lower 

 limbs the superficial lymphatic vessels I I I I, which lie beneath the 

 skin, are represented. In the left upper and lower limbs the deep 

 lymphatic vessels which accompany the deep blood-vessels are shown. 

 The lymphatic vessels of the lower limbs join the thoracic duct at 

 the spot where the lacteals open into it ; those from the left upper 

 limb and from the left' side of the head and neck op^en into the thoracic 

 duct at the root of the neck. The lymphatics from the right upper 

 limb and from the right side of the head and neck join the great 

 veins at n. At m m are seen the enlargements called lymphatic glands, 

 situated in the course of the lymphatic vessels.
