What is usually the first branch of the SMA?
inferior pancreaticoduodenal artery
15-18 arteries to the jejunum and ileum
intestinal arteries
The straight terminal ends of the intestinal arteries are called what? What connects adjacent intestinal arteries?
vasa rectae
arcades

long vasa rectae
Near the distal ileum, 4-5 arcades are found between adjacent intestinal arteries yielding what?
short vasa rectae
What artery supplies the distal ileum, cecum, appendix, and proximal ascending colon?
ileocolic artery
What artery supplies the ascending colon and has superior/inferior branches?
right colic artery
What artery supplies the transverse colon, diving into right and left branches?
middle colic artery

right side, retroperitoneal position
anterior, transverse mesocolon
The duodenojejunal junction has a sharp bend and a fibromuscular ligament from the right crus of the diaphragm, the ______, which anchors the small intestine to the diaphragm.
suspensory ligament of the duodenum - this ligament passes posterior to the pancreas
