    accompanied by numerous sympathetic nerves and lymphatics. The arrangement of the system facilitates a slow and even flow of blood from the digestive organs. Tributaries :— 1. Splenic vein (S'.Y) formed by several veins from the hilus of the spleen. It passes through the lieno-renal ligament and unites behind the pancreas with the inferior mesenteric vein. It receives (a) vasa brevia (Y.B) from the body of the stomach ; (b) left gastro-epiploic vein (L.G.E.Y) which runs along the greater curvature of the stomach, receiving veins from it, and connects the splenic and duodenal veins; (c) pancreatic veins. 2. Inferior mesenteric vein (I.M. Y), which communicates with the superior mesenteric vein by a vessel which runs through the transverse meso-colon and supplies the transverse colon (T.M.C.Y). It drains the large bowel from the splenic flexure to the beginning of ’the rectum, and it unites with the splenic vein. 3. Superior mesenteric vein (S.M.Y), which drains the ileum and jejunum, and the large intestine from the appendix to the hepatic flexure, communicates with the venous arch in the trans- verse colon. At the point where it participates in the formation of the portal vein it receives the venous arch of the transverse colon, duodenal veins (d.v) and gastric veins (g.v). 4. The cystic vein (c.v) enters the portal trunk itself. The Inferior Caved System. The vena eava inferior is formed by the union of the two common iliac veins deep to the right common iliac artery. It ascends on the right side of the abdominal aorta. In the upper part of the abdomen it bends to the right and passes through a tunnel in the liver. Its relations are much as in the human body, but the right ovarian artery passes behind it. It receives:— 1. Four single lumbar veins, the first or lowest entering the left side of the vein, and the others pass into its dorsal surface. 2. Right ovarian vein. 3. Two renal veins. 4. Right suprarenal vein. 5. Gastric vein which serves as a link between the systemic and portal circulations. 6. Hepatic veins. Veins of the Pelvic Extremity. Superficial Veins ;—The venous arch on the dorsum of the foot receives veins from both sides of the digits. The inner extremity is continued upwards by two internal saphena veins, which are united by cross branches. They pass upwards, dip under the sartorius and end in the femoral vein. The large external saphena vein runs up the back of the leg, dips through the fat L72]
