the recurrent intestinalis, all of which lie to the right of the spleen, 

 under the left lobe of the liver, and along the left side of the stomach. 

 The recurrent sinister (Fig. 64, No. 20) gives arterial branches to 

 the proventriculus, the gizzard, the pyloris, and the left lobe of the 

 liver. The anterior or recurrent dexter (Fig. 64, No. 21) gives off a 

 renal artery and from four to six splenic arteries. 



The recurrent intestinalis artery (Fig. 64, No. 24) arises on the 

 posterior of the stomach within the duodenal loop, and supplies 

 the duodenum and the pancreas (Fig. 63, No. 7). It gives off a 

 branch, called the recurrent iUo-coUcus (Fig. 64, No. 25), which 

 supplies the large intestines, including the caeca. 



The arteria hepatica dextra (Fig. 64, No. 22) is a branch from the 

 ceUac axial trimk. It gives several branches to the right lobe of 

 the hver and to the gall-bladder. The gastric branches pass to 

 the muscles of the stomach. The anterior and posterior recurrent', 

 branches often anastomose. | 



The anterior mesenteric artery (Fig. 63, No. 5; Fig. 64, No. 2$j; 

 originates from the posterior aorta near the generative glands. It; 

 is directed downward, and divides into many branches which pass' 

 in the mesentery toward the intestines. Recurrent branches (Figl 

 64, No. 27) are given off, which anastomose, forming mesenteric 

 arches., From these arches are given off branches which supply the 

 intestinal walls. 



The anterior mesenteric artery gives off the recurrent ilio-celiacus 

 (Fig. 64, No. 28) which is distributed to the caeca; other of its 

 branches are distributed to the small intestine. 



The anterior mesenteric artery extends along the small intestine 

 and ends in the recurrent superior hemorrhoidal arteries (Fig. 64, No. 

 29) which anastomoses on the surface of the rectum with a branch 

 of the posterior mesenteric artery. 



Branches from the anterior mesenteric artery also anastomose 

 with branches of the celiac axis. 



The posterior mesenteric arteiy (Fig. 64, No. 30) is given off from 

 the posterior aorta posterior to the origin of the anterior mesenteric 

 and near the arteries of the thigh and is distributed to the lesser 

 mesentery supplying the large intestine. Branches of the superior 

 hemorrhoidal arteries anastomose with branches of the posterior 

 mesenteric artery. Branches from this source are called the median 

 hemorrhoidal (Fig. 63, No. 6). 



The posterior mesenteric artery (Fig. 64, No. 30) also gives off a
