Comments	"The approximately 7-m long GI tract can be divided in several anatomically distinct regions, starting from the mouth, via the esophagus to the stomach, proceeding to the small intestine (divided into duodenum, jejunum and ileum, respectively) and the large intestine (divided into cecum, colon [with an ascending, transverse, descending and sigmoid part] and rectum, respectively) and ending at the anus (Figure 1)."
