the inferior mesenteric, the supra-renal, the renal, and the sper- 

 matic or ovarian arteries, while in the latter are included the 



phrenic, the lumbar, and the 

 middle sacral arteries. 



The coeliac artery, or axis, 

 is a short, wide vessel, usually 

 not iribre than half an inch in 

 length, which arises from the 

 front of the aorta, close to the 

 opening in the diaphragm. It 

 divides into three branches; 

 viz. the gastric, which supplies 

 the stomach ; the hepatic, 

 which supplies the liver ; and 

 the splenic, which supplies the 

 spleen, and in part the stom- 

 ach and pancreas. 



The superior mesenteric ar- 

 tery arises from the fore part 

 of the aorta, a little below 

 the coeliac axis. It supplies 

 the whole of the small intes- 

 tine beyond the first portion 

 (the duodenum) close to the 

 stomach, and half of the large 

 intestine. 



The inferior mesenteric ar- 

 tery arises from the front of 

 the aorta, about an inch and 

 a half above its bifurcation, 

 and supplies the lower half 

 of the large intestine. Con- 

 tinued under the name of the 

 superior hemorrhoidal artery,

The renal arteries are of 

 large size, in proportion to 

 the bulk of the organs which they supply. They arise from the 

 sides of the aorta, about half an inch below the superior mesen- 

 teric artery, that of the right side being generally a little lower
