Jejunal, ileal, ileocolic, right colic and middle colic veins
Tributary · Midgut
The veins of the midgut accompany the branches of the superior mesenteric artery in the mesentery and transverse mesocolon: jejunal and ileal veins from the small bowel, the ileocolic vein (receiving the appendicular vein) from the terminal ileum, caecum and appendix, and the right and middle colic veins from the ascending colon and the proximal two-thirds of the transverse colon. All end in the superior mesenteric vein.
