You selected: descending aorta

The aorta is the largest vessel of the body. The abdominal aorta gives rise to branches supplying blood to the abdominal organs. These branches include the celiac trunk which supplies blood to the stomach, liver, spleen, and pancreas, the superior mesenteric artery, which supplies the small intestine and part of the colon, and the inferior mesenteric artery which supplies blood to the left side of the colon.

Last modified: Feb 2nd, 1997 introduction=This transverse sectiion lies approximately 5cm above the umbilicus (belly button). Note the posterior location of the kidneys, and their encasement in the perirenal fat. Segments of small intestine and colon may also be seen. Small bowel can be distinguished from the colon by it's narrower bore, and smaller lumen. This particular section cuts through the ascending colon, seen on the right, the transverse colon, located in the middle, and the descending colon shown posteriorly on the left side of the body. Click on 'colon' in the key points listed below to have these features outlined in the image.

Muscles of interest include the psoas major and quadratus lumborum muscles, the erector spinae muscles of the back, and the muscles of the anterior abdominal wall: external and internal obliques, transversus abdominus, and rectus abdominus muscles.
