Final answer:
Collateral circulation between celiac and superior mesenteric arteries is provided by pancreaticoduodenal arteries, while ileocolic, right colic and middle colic branches facilitate anastomoses between superior and inferior mesenteric arteries.
Step-by-step explanation:
Anastomoses between the celiac and superior mesenteric arteries include the pancreaticoduodenal arteries. Anastomoses between the superior mesenteric and inferior mesenteric arteries involve the ileocolic, right colic, and middle colic branches.
The celiac artery primarily supplies the liver, stomach, and duodenum, branching from the abdominal aorta. The superior and inferior mesenteric arteries supply the small and large intestines, respectively. Anastomoses play a critical role, in ensuring collateral circulation and maintaining blood supply to the gastrointestinal tract even if one artery is occluded.
