Introduction

This section of notes gives an introductory overview of intestinal development. In studying this part of the GIT much emphasis is placed upon the initial herniation of the midgut loop during development and its subsequent rotations to achieve the correct anatomical position (More? Abnormalities - Intestinal Malrotation).

There is more than the physical looping and you should also consider the differentiating physiological functions of the small and large intestine, their associated vascularisation and mesenteries and associated specialized regions (immune Peyers patches).

Finally, consider the early postnatal maturation that occurs with population of the gut with colonizing microbiota (Enterococcus faecalis, etc.) and the role in early immune function in absorbtion of maternal immunoglobulin.
