Introduction
The intestine is one of the most active and complex organ systems in the body. As an example of its complexity, it is notable that the system contains neural tissue equivalent to the entire spinal cord. The intestine is involved in important endocrine and exocrine roles and also serves as the largest and most active immune organ of the body. In addition to the intestine itself, the luminal microbiota and its interactions with the intestinal mucosa and submucosa are becoming increasingly recognized as critical in postnatal development and lifelong health and disease. In addition to these seemingly newfound GI tract functions, its classic role in digestion and absorption of nutrients remains of utmost importance in health and needs to be understood in order to optimize nutrition during these highly critical windows of development.
Dramatic events in gastrointestinal (GI) system development begin in the 3rd week of fetal development. Gastrulation, organ formation, growth,...
