Your digestive tract is made up of different organs and segments, which develop from what is called the ``primitive gut'' in an embryo. The top part or foregut develops into the esophagus, stomach, and duodenum, which is the first part of the small intestine. The middle part or midgut develops into your jejunum and ileum, the middle and lower parts of your small intestine. The bottom section or hindgut develops into your colon. As seen from the anterior or front, the colon goes upwards from the small intestine as the ascending colon, crosses and is attached to your stomach as the transverse colon, and then goes down to the rectum as the descending colon. It is supplied with blood by the mesenteric artery.
