TIPSImportant Question from NEET PG

Answer : D. Gastroduodenal artery
Explanation : 

The right gastroepiploic artery, arises from the gastroduodenal artery behind the first portion of the duodenum.

  • The celiac axis supplies blood to the stomach and duodenum.  The SMA supplies the small bowel from the distal duodenum to the mid-transverse colon. The inferior mesenteric artery supplies the transverse colon to the rectum.
  • The superior and inferior pancreaticoduodenal vessels are collaterals that connect the celiac axis to the SMA.
  • The phrenic artery connects the aorta to the celiac axis.
  • The marginal artery of Drummond and the arc of Riolan are collaterals that connect the SMA and the IMA.
  • Griffith point in the splenic flexure and Sudeck point in the rectosigmoid area are watershed areas within the colonic blood supply and common locations for ischemia.
