the common iliac arteries, and these are sometimes spoken of as the 

 eommon iliac glands. The median lumbar glands receive their 

 afferent vessels from the following sources : (i) the external iliac 

 glands ; (2) the internal iliac glands ; (3) the sacral glands ; (4) the 

 efferent lymphatics of the testes in the male, and of the ovaries, 

 Fallopian tubes, and upper end of the uterus in the female ; (5) the 

 kidneys ; (6) the suprarenal capsules ; (7) the vertebral part of the 

 diaphragm ; and (8) some of the efferent vessels of the lateral 

 lumbar glands. Their efferent vessels unite to form two lumbar 

 lymphatic trunks, right and left, which open into the lower end of

the receptaculum chyli on a level with the body of the second 

 lumbar vertebra. The left trunk receives the lymphatics of the 

 lower part of the left colon, iliac colon, and pelvic colon. 



The lateral lumbar glands are small but very numerous, being 

 about twenty in number. They are situated behind the psoas 

 magnus, where they lie between the lumbar transverse processes, 

 and they receive their afferent vessels from the following sources : 

 (i) the posterior abdominal wall and deep muscles of the back, and 

 (2) the spinal canal. Some of their efferent vessels join the right 

 and left lumbar lymphatic trunks, whilst others open independently 

 into the lower end of the receptaculum chyli.
