It shows also the relation of the lymphatics to the pancreas. It is to be noted that the spleen, with the lymphatic vessels in its capsule and mesentery, has been removed and that the gastro-splenic trunk has been cut just as it is dividing into its two terminal branches. The intestines have been removed, leaving only the stump of the superior mesenteric trunk. This gastric trunk terminates at the lesser curvature b}' dividing into two branches: (1) an ascending or left branch, which supplies the cardiac region of the stomach, forms a network of periesophageal lymphatics, and sends out vessels to the medial portion of the diaphragm; (2) a descending or right branch, which likewise supplies the cardiac region, diaphragm and lesser curvature (fig. 2, V. 1. diaph.; T. c. v. min.), and anastomoses with other vessels supplying the diaphragm and lesser curvature. The left trunk, of which the main branch is the gastro-splenic trunk (fig. 3), passes ventrally to the fundus of the stomach. Near its origin it sends lymphatics to the tail of the pancreas. It continues on to the fundus as the gastro-splenic trunk, then divides beneath the posterior third of the spleen, one branch im- , ^;...^V^SS"f!^£^V???W2! / VI pvl. '?|i| V.
