The gastric artery refers to a group of blood vessels that supply oxygenated blood to the stomach. There are two main gastric arteries: the left gastric artery and the right gastric artery. These arteries branch off from the celiac trunk, which is a major artery that supplies blood to the abdominal organs. The left gastric artery runs along the lesser curvature of the stomach, while the right gastric artery supplies the lower part of the stomach. Proper blood flow through these arteries is essential for the stomach's health and function, supporting digestion and nutrient absorption.
