These articles are not exactly the same, but the intestine article is subsumed within the gastrointestinal tract article. 'Intestines' could be integrated in an artful way, and without a merge, these articles will simply exist to mirror and duplicate each others' content, without benefiting readers. Thoughts?

Agree There are already informative pages on the subdivisions. There does not need to be a separate page for intestine(s). It seems that Human gastrointestinal tract already fills the role of being the overarching article which sums up and branches out. More effort should be put into cleaning that up into a tighter article and making the "sub-"articles better. The Haztalk 18:17, 2 March 2014 (UTC)
A separate page is badly needed for digestive system. DIgestive system All other systems have their own entry page. Digestive system at the moment redirects to 'digestion' which is just a process of the digestive system. Infobox on this GI page refers to digestive system - which doesn't exist anywhere Iztwoz (talk) 12:44, 5 March 2014 (UTC)
Agree that this is an extremely confusing state of affairs. We do need a separate digestive system article. A good place to start may be splitting some of the content (esp. the summary of human organs) from the Digestion article into a separate Digestive system article. --LT910001 (talk) 21:28, 5 March 2014 (UTC)

Medical articles about the colon refer to "proximal vs. distal adenomatous polyps" -- which parts of the colon are considered proximal or distal (in relation to what?) -- please add these terms to the article. -18.104.22.168 (talk) 17:37, 16 November 2014 (UTC)
'Adenomas were classified as “proximal” if in the cecum, ascending colon, hepatic flexure, or transverse colon; they were classified as “distal” if in the splenic flexure or below.' -22.214.171.124 (talk) 17:51, 16 November 2014 (UTC)
90% of the text under subheading function in 2015-Mar-13 version  is about immunity. That may gives the wrong impression, as if the intestine is more about defense than digestion. Should be remedied by adding meaningful detail about digestion here.
