Which artery supplies the foregut derivatives in the gastrointestinal tract?

The celiac artery is the primary vessel responsible for supplying blood to the foregut derivatives in the gastrointestinal tract. The foregut encompasses structures such as the esophagus, stomach, proximal duodenum, liver, gallbladder, and pancreas. The celiac artery branches into several major arteries – including the left gastric artery, splenic artery, and common hepatic artery – that further supply these essential organs.

Understanding the anatomical relationships and blood supply is crucial for various clinical scenarios, such as surgeries involving these organs or addressing conditions like ischemia. The celiac artery's role in vascularizing the foregut makes it a key focus in the study of gastrointestinal physiology and pathology.
