524 A MANUAL OF ANA TOMY. 



On the outside, the right lies against the liver for its 

 upper three-fourths, the left against the spleen for about the 

 same extent. Above, the suprarenal bodies rest upon the 

 upper and inner margin of the kidneys. On the inner side 

 are the arteries, veins, and exit of the ureters. 



The arteries are derived from the Aorta. The veins 

 empty into the Vena Cava. The nerves are derived from 

 the solar and aortic plexuses. The lymphatics empty into 

 the receptaculum chyli. 



The Suprarenal Bodies. Figs. 1 06, 107. 



These small triangular glands are found resting upon the 

 upper and inner borders of the kidneys. Their base is 

 about one and three-fourths inches, their height about one 

 and one-fourth inches. 



The right suprarenal body is behind the liver, duodenum, 

 and in contact with the vena cava, the left behind the 

 stomach, pancreas, splenic artery, and has the spleen to the 

 outer side. 



The arteries are from the Aorta, Inferior Phrenic, and 

 Renal. The veins empty into the vena cava, or renal. The 

 nerves are derived from the same source as the kidney. 

 The lymphatics pass to the renal glands. The kidneys 

 and suprarenal bodies are behind the peritoneum. 



The Ureters. Figs. 105 to 107, 112. 



Are the excretory ducts of the kidneys, and pass down- 

 ward to empty into the base of the bladder. They are 

 from twelve to sixteen inches long, and below the kidney 

 one-sixth of an inch in diameter. At the kidney they 

 become expanded to form the sinus, into which the calices 

 empty. In its course to the bladder the ureter crosses the 

 psoas muscle, genitocrural nerve, common iliac artery and 

 vein. It lies behind the peritoneum, and is crossed by the
