The celiac trunk is a major artery that branches off from the abdominal aorta. It supplies blood to several important organs in the upper abdomen, including the stomach, liver, spleen, and parts of the pancreas and intestines. The celiac trunk typically divides into three main branches: the left gastric artery, common hepatic artery, and splenic artery. This artery plays a crucial role in the body's digestive system by ensuring that these organs receive the necessary oxygen and nutrients. Any blockage or damage to the celiac trunk can lead to serious health issues, affecting digestion and overall organ function.
