LYMPHATICS OF THE MAMMARY GLAND 



227 



From intestines through mesenteric glands to the thoracic duct; from all 

 remaining abdominal organs to the thoracic duct (except upper surface of 

 the liver). 



All lymph which flows through lum- 

 bar glands runs to the thoracic duct, and 

 through it to the left subdavian vein. 



Note. The lymphatics in the mesen- 

 tery, coming from the small intestine, 

 convey not only lymph but chyle also, 

 which is light in color and gives to them a 

 milky appearance, therefore their name, 

 lacteals (Fig. 153). 



ABOVE THE DIAPHRAGM, LEFT SIDE 



From the left upper extremity through 

 axillary and subdavian glands to the deep 

 cervical glands, thence to thoracic duct. 



From left head and neck, superficial : 

 face and scalp, to occipital, submaxillary, 

 superficial cervical, and then deep cervical 

 glands. Deep : face, throat and neck, to 

 deep cervical glands and thence to thoracic 

 duct. 



From the left thorax, walls and vis- 

 cera (including left half of heart), to 

 thoracic duct. 



ABOVE THE DIAPHRAGM, RIGHT 

 SIDE 



From the right upper extremity 



through axillary, subdavian, and deep 

 cervical glands, to the right lymphatic duct 

 (p. 228). 



From the right head and neck through 

 occipital, submaxillary, superficial and deep 

 cervical glands, to right lymphatic duct. 



From the right thorax, walls and vis- 

 cera (including right half of heart), to 

 right lymphatic duct.
