   • MIDDLE SUPRARENAL
     • can branch off the aorta
   • Splenic
     • Posterior Gastric
     • L Gastro-epiploic
       • Superior Part Greater Curvature Tummy
     • Short Gastric A
       • Fundus of Tummy
   • L Gastric
     • Esophageal
       • Abdominal Esophagus
     • Lesser Curvature Tummy
   • Common Hepatic
     • R Gastric A
     • Hepatic A Proper
       • R/L Hepatic A
         • Cystic A

         • Inferior Part Greater Curvature Stomach
       • Superior Pancreaticoduodenal (Post/Ant)
         • Pancreas + Duodenum

3. RENAL A

   • R side is longer than L cuz passes behind across inferior vena cava (width of inf vena cava is how much longer R is than L)
   • There may be 3+ renal A supplying kidney
   • branches do not anastomose but the veins do

   • R Colic
   • Ileocolic
   • Inferior Pancreaticoduodenal (Post/Ant)

5. INFERIOR MESENTERIC

   • Hindgut= descending colon, sigmoid colon, rectum
   • Anastomose with Superior Mesenteric around border of lrg intestine-> Marginal A
   • Retroperitoneal
   • L Colic
   • Sigmoid
   • Superior Rectal
     • Branches into smaller arteries to supply the rectum + anal canal

6. GONADAL (TESTICULAR/OVARIAN)

   • Pass anterior to IVC

7. COMMON ILIAC

   • Internal Iliac
     • Middle Rectal
       • Anastomose with superior and inferior rectal to supply rectum and anal canal
     • Internal Pudenal
