Vasa recta are straight arteries coming off from arcades in the mesentery of the jejunum and ileum, and heading toward the intestines.
The arcades are anastomoses of the jejunal and ilial arteries, branches of superior mesenteric artery.
Loop of small intestine showing distribution of intestinal arteries.
left gastric: esophageal branches
splenic: pancreatic branches (greater, dorsal) – short gastric – left gastro-omental
common hepatic: proper hepatic (cystic), right gastric, gastroduodenal (right gastro-omental, superior pancreaticoduodenal, supraduodenal)
inferior pancreaticoduodenal – intestinal (jejunal, ileal, arcades, vasa recta) – ileocolic (colic, anterior cecal, posterior cecal, ileal branch, appendicular) – right colic – middle colic
left colic – sigmoid – superior rectal – marginal
visceral: middle suprarenal – renal (inferior suprarenal, ureteral) – gonadal (testicular ♂ / ovarian ♀) parietal: inferior phrenic (superior suprarenal) – lumbar – median sacral terminal: common iliac (IIA, EIA)
umbilical (superior vesical, to ductus deferens) – middle rectal – obturator (anterior branch, posterior branch) – inferior gluteal (accompanying of ischiadic nerve, crucial anastomosis)
uterine ♀ (helicine, vaginal of uterine, ovarian of uterine, tubal of uterine) – vaginal ♀ / inferior vesical ♂
internal pudendal: inferior rectal – perineal (urethral) – posterior scrotal ♂ / labial ♀ – bulb of penis ♂ / vestibule ♀ – deep artery of the penis ♂ (helicine) / clitoris ♀ – dorsal of the penis ♂ / clitoris ♀
iliolumbar (lumbar, iliac) – lateral sacral – superior gluteal
inferior epigastric (cremasteric, round ligament) – deep circumflex iliac – femoral
