The celiac trunk, also known as the celiac artery or the celiac axis, is a major branch of the abdominal aorta. Arising just below the diaphragm, it is responsible for supplying blood to various organs in the abdominal region, including the stomach, liver, spleen, and parts of the small and large intestines.
Originating from the anterior surface of the abdominal aorta, just below the diaphragm, the coeliac trunk is a short, thick vessel that arises as a single trunk before dividing into three main branches: the left gastric artery, the splenic artery, and the common hepatic artery. Each of these branches further divides into smaller vessels, forming an extensive network of blood supply within the abdominal cavity. The left gastric artery supplies the stomach and contributes to the esophageal arterial network. The splenic artery provides blood to the spleen, pancreas, and parts of the stomach. The common hepatic artery supplies the liver, gallbladder, stomach, and duodenum.
The left gastric artery, the smallest branch of the coeliac trunk, courses along the lesser curvature of the stomach. It gives off branches that anastomose with the right gastric artery, forming a rich network of blood vessels along the stomach's lesser curvature. The left gastric artery also contributes to the formation of the esophageal arterial network, providing collateral circulation to the lower part of the esophagus. This collateral circulation is crucial in cases of impaired blood flow to the lower esophagus, such as in portal hypertension or esophageal varices.
The splenic artery, the largest branch of the coeliac trunk, takes a tortuous course toward the spleen, giving rise to numerous branches along its path. It supplies blood to the spleen, pancreas, and parts of the stomach. Along its path, the splenic artery gives off multiple branches, including short gastric arteries that supply the fundus and upper part of the greater curvature of the stomach. Additionally, the splenic artery provides blood supply to the pancreas through various pancreatic branches. It also gives rise to numerous branches that supply the spleen, including the short gastric arteries, left gastroepiploic artery, and pancreatic branches. Within the spleen, the splenic artery branches into several smaller vessels that penetrate the splenic parenchyma, forming the splenic pulp. This network of vessels facilitates the filtration of blood and the removal of old or damaged blood cells by the spleen.
The common hepatic artery, the last branch of the coeliac trunk, further divides into the proper hepatic artery and the gastroduodenal artery. The proper hepatic artery supplies the liver and gives rise to the left and right hepatic arteries. The hepatic artery system is responsible for delivering oxygenated blood to hepatocytes, which is crucial for their metabolic functions. The proper hepatic artery also gives off the cystic artery, which supplies blood to the gallbladder. This artery is important for maintaining a healthy blood supply to the gallbladder, allowing it to store and release bile as needed for digestion. The gastroduodenal artery, on the other hand, courses toward the pylorus of the stomach and gives off branches that supply the stomach and the first part of the duodenum. It provides arterial supply to the pyloric region of the stomach, contributing to its blood circulation. The gastroduodenal artery also gives off the right gastroepiploic artery, which courses along the greater curvature of the stomach, providing blood supply to this region.

What about superior masentric artery
and
inferior masanteric artery
