vature of the stomach, dividing into numerous branches and. 
anastomosing with the gastrica sinistra. The pancreaticoduo- 
denalis superior (7) passes to the duodenum, supplying it and 
the duodenal part of the pancreas and anastomosing with the 
pancreaticoduodenalis inferior (4). The gastroepiploica dextra 
(2) passes along the greater curvature of the stomach from the 
pyloric end and supplies the walls of the stomach, sending 
branches also to the ascending limb of the great omentum. 
These branches anastomose with the terminal branches of the 
splenic artery. 
2. A. gastrica sinistra (¢).—This arises from the cceliac 
artery and passes to the lesser curvature of the stomach, 
extending along this to the right. It gives off many branches 
to the walls of the stomach, and anastomoses with A. pylorica. 
A. ventriculi dorsalis (/).—One or two small arteries 
which arise either from the gastrica sinistra or the cceliac 
artery, and pass toward the dorsal part of the greater curvature 
of the stomach near its cardiac end. 
3. A. lienalis (/).—The splenic artery is the largest of the 
branches of the cceliac axis, of which it appears to be the direct 
continuation. It divides into two large branches, one to the 
cranial end, the other to the caudal end, of the spleen (1): 
From the latter a large branch passes to the pancreas and 
descending limb of the great omentum. 
B. A. mesenterica superior (Fig. 126, 2).—The superior 
mesenteric artery is larger than the cceliac. It supplies the 
blood to the small intestines and caudal portion of the pancreas 
and to the ascending and transverse colon. It arises from the 
ventral side of the abdominal aorta about one centimeter 
caudad of the coeliac axis and passes caudoventrad, forming a 
curve with the convexity dextrad. It gives off the pancrea- 
ticoduodenalis inferior, colica media, colica dextra, ileocolica, 
and numerous branches to the small intestine. 
1. A. pancreaticoduodenalis inferior (Fig. 125, £).—This 
passes to the caudal end of the pancreas and a part of the 
duodenum, anastomosing with the pancreaticoduodenalis 
superior. : 
2. A. colica media is a large branch to the transverse and
