Gastrointestinal Tract - Postnatal

From Embryology
Revision as of 15:28, 2 May 2011 by S8600021 (talk | contribs) (Introduction)


This page is an introduction to postnatal gastrointestinal tract development. This nutritionally involves a change from prenatal placental vascular nutrition to postnatal oral colostrum/milk enteral nutrition (enteral = nutritient delivery as fluid into the gastrointestinal tract). Also look at the topic of Milk in relationship to neonatal nutrition. The postnatal gastrointestinal tract development is also about increased activity of the tract and associated organs as well as the populating with intestinal flora in the tract.

These notes should be read in conjunction with the related page on Milk and an understanding of prenatal Gastrointestinal Tract Development.

Some Recent Findings

Lipid Signalling

Lipids present in the intestine leads to a reduction in nutrient intake. Recent research has shown that lipids present in the intestine can also regulate endogenous nutrient production.[2]

Signalling pathway:

presence of ingested lipids

intestinal lipid sensors

signal to the brain


reduction in endogenous glucose production
