Artery Mesenteric Superior

Arterial system of the superior mesentery

Arterial systems are an important component of the human body. Arteries deliver oxygen and nutrients to the body's tissues and organs, and remove waste and metabolic products. The inferior mesenteric artery is a type of artery that originates from the aorta and descends into the pelvic mesentery, where it divides into many smaller branches, supplying blood to the intestines, pelvic organs, and mesentery. The superior mesenteric artery is anatomically similar to the inferior one. However, it passes through the abdominal cavity, passing through the diaphragm, then into the celiac angle, then it is the mesenteric artery. The superior mesenteric artery here becomes the main supplier of oxygen to the heart. The artery then continues down and gives off several branches to supply the abdominal and pelvic organs. In most cases, the artery is attached to the colon, which facilitates its further division into branches that supply the remaining parts of the mesenteric region, including the stomach, spleen, liver, gallbladder, bladder, etc. The article will discuss arterial branching using the example of the superior mesenteric artery , but this information also applies to the inferior mesenteric artery. **Anatomy** The superior mesenteric artery is a long and thick caval artery that is located in the retroperitoneal space in the abdominal cavity. The artery begins at the point where the left side of the convex surface of the diaphragm crosses the left border of the stomach and spleen. While inside the diaphragm, the artery makes a loop and continues its path below the right border of the stomach and gland. The artery passes through the diaphragmatic transverse meridian into the pelvis. Here she comes down forward

The pectoralis major muscle, or foramen quadrate major, serves as the exit site for the abdominal aorta and the superior suprarenal artery. Near the posterior border of the pectoralis major muscle from top to bottom there is the inferior epigastric foramen, in which the superior epigastric vessels from the abdominal aorta, as well as other vessels of the peritoneum, pass
