and vena azygos major, under the right cms of the diaphragm. 

 It ascends through the aortic opening of the diaphragm and 

 then along the spine to empty into the left innominate vein. 

 It drains the lower half of the body. [906] 



The deep glands are in two groups, visceral and parietal. 



The visceral glands are the following : gastric, in three groups, 

 one (coronary) lying along the lesser curvature of the stomach 

 and behind the cardiac orifice, one (sub-pyloric) along the 

 greater curvature near the pylorus, and the third (retro-pyloric) 

 behind the pylorus and first part of the duodenum; splenic, 

 lying at the hilus of the spleen; hepatic, lying below the trans- 

 verse fissure of the liver in the small omentum; pancreatic, 

 lying along the upper border of the pancreas ; superior mesen- 

 teric, lying in the mesentery, especially the jejunal; ileo-ccecal, 

 lying in the lowest part of the mesentery, between the ileum 

 and ascending colon; rectal, lying in the meso-rectum; inferior 

 mesenteric, lying along that artery and its branches; colic, 

 lying in the meso-colon; and coeliac, lying around the coeliac 

 axis and adjacent part of the aorta. [918] 



The parietal glands are the following: External iliac, lying 

 on either side and in front of that artery in three groups, outer, 

 middle, and inner, of which the latter extends into the pelvic 

 cavity as far as the obturator nerve; obturator (inconstant), 

 lying at the back of the obturator canal; circumflex iliac and 

 epigastric (inconstant), lying along the deep circumflex iliac 

 and deep epigastric arteries ; supra- and infra-umbilical (incon- 

 stant), lying on the posterior surface of the Rectus sheath, 

 above and below the umbilicus ; internal iliac, lying along that 

 artery, on the pelvic wall below the obturator nerve; lateral 

 sacral, lying on the front of the sacrum internal to the anterior 

 sacral foramina ; common iliac, lying along that artery ; lumbar 

 (inconstant), lying on the lumbar transverse processes behind 

 the Psoas; and aortic, lying along all sides of the abdominal 

 aorta and therefore known as the pre-aortic, lateral aortic, and 

 retro-aortic glands. [920]
