226 ANATOMY AND PHYSIOLOGY 



Neck: Superficial cervical, near the external jugular vein; 

 deep cervical, with the large vessels (carotid arteries and internal 

 jugular vein.) (Important.) 



Thorax: Mediastinal, with the vessels in the mediastinum; 1 

 bronchial, with bronchial tubes and vessels these are numerous.

COURSE OF THE LYMPH STREAM 



BELOW THE DIAPHRAGM 



Knowing the location of the glands, and remembering that lymph flows 

 toward the heart, the course of the stream is easily understood. 



From the lower extremity up through popliteal, saphenous, and inguinal 

 glands to the external iliac, and thence to the lumbar glands. 



From the buttock and anterior parts of the genital organs to the inguinal, 

 external iliac, and thence to the lumbar glands. 



In the deeper parts of the genital organs to the internal iliac, and thence 

 to the lumbar glands. 



From the pelvic organs or viscera to the internal iliac, and thence to lumbar 

 glands. 



The ovaries, tubes, and fundus of the uterus send their lymph directly to 

 the lumbar glands, instead of first through the internal iliac. 



From the abdomen, lymph from the abdominal walls flows to lumbar 

 glands (sometimes indirectly), also from the kidneys and adrenals to the 

 lumbar glands.
