_____ supplies the jejunum, ileum, cecum, ascending colon, portions of the transverse colon and head of the pancreas?

_____ supplies the jejunum, ileum, cecum, ascending colon, portions of the transverse colon and head of the pancreas?

• A. SMA
• B. IMA
• C. Celiac Trunk
• D. Renal Artery

Answer: (A)

The main concept is the arterial supply pattern for the gut: midgut structures rely on the superior mesenteric artery. Jejunum and ileum are classic midgut derivatives, as are the cecum and ascending colon, with the proximal portion of the transverse colon also receiving SMA branches. The head of the pancreas gets blood via pancreaticoduodenal arteries that connect with the SMA system, reinforcing its midgut territory. That’s why this artery is the best fit. The other vessels don’t cover this whole set: the IMA supplies hindgut structures (distal transverse colon to rectum), the celiac trunk supplies foregut structures (stomach, liver, spleen, and pancreas head via other pancreaticoduodenal connections), and the renal artery supplies the kidneys.
