The splenic or terminal branches of the splenic artery pass 

 from the lieno-renal ligament 

 into the hilum of the spleen.

From the above description of the 

 branches of the coeliac artery it will 

 be seen that the stomach is remarkably 

 rich in blood-vessels. Two proceed 

 from left to right viz. the left gastric, 

 along the lesser curvature, and the left 

 gastro-epiphic, along the greater curva- 

 ture; two, both branches of the hepatic, 

 are directed from right to left viz. 

 the right gastric, in relation to the 

 lesser curvature ; and the right gastro- 

 epiploic, in relation to the greater 

 curvature. The arterial circle is com- 

 pleted on the left by the short gastric 

 arteries, which connect the left gastric 

 artery with the left gastro-epiploic. 



The splenic vein, the portal 

 vein, the bile duct, and the 

 inferior phrenic arteries will be 

 considered at a later stage of 

 the dissection. 



Ventriculus. The 

 stomach is the most Thoracic duct _ 



dilated Section Of the i2th thoracic vertebra 



alimentary canal. Its 

 size, shape and position vary 

 considerably in association with 

 the amount of its contents, and 

 with the empty or distended 

 condition of the adjacent hollow 

 viscera, but, on the whole, it is 

 pear-shaped, and it is customary 

 to recognise the following parts : 

 (i) a blunt left upper extremity 

 or fundus ; (2) a narrow lower 

 and right extremity or pylorus ; 

 (3) an intermediate part separ- 

 ated into cardiac and pyloric 

 portions; (4) two orifices, an cesophageal and a pyloric; (5) 

 two surfaces, a superior and an inferior ; (6) two borders or 

 curvatures, a greater and a lesser.
