What does the left gastric artery supply blood to?

The left gastric artery is a vital vessel that primarily supplies blood to the stomach, particularly its upper part, known as the cardia. This artery originates from the celiac trunk, which is the main arterial supply to the abdominal organs. By traveling along the lesser curvature of the stomach, the left gastric artery ensures proper blood circulation essential for the stomach’s functions, including digestion and nutrient absorption.

Understanding the left gastric artery's role is crucial in the context of gastrointestinal circulation and surgery, as maintaining blood flow to the stomach is important during procedures that may affect this region. In contrast, the other listed structures have different arteries supplying them, such as the hepatic artery for the liver, the splenic artery for the spleen, and the renal arteries for the kidneys. Hence, the correct answer reflects the specific anatomical and functional relationship between the left gastric artery and its primary target organ, the stomach.
