You selected: colonThis section nicely shows the ascending, transverse, and descending colon. The ascending colon lies on the right side of the body. Of the three segments, it is the closest to the ileum, the distal region of the small intestine. The ascending colons plays an important function in retrieving solutes and water from the material entering from the ileum.
The transverse colon lies in the anterior region of the section, while the descending colon lies more laterally on the left side of the body.

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.
