Abstract

The requirements of nutrients for children are different from adults′,and the digestive functions in children are immature.In the present review,the progress on developmental physiology of children in digestive system related to oral,gastric motility,and enzymes secretions were summarized.The main features include a higher pH in gastric fluid,a lower enzymes output and activities in secretions in stomach and pancreas,a slower gastric empty rate and intestinal motility,and the immature of intestinal barrier than those in adults.This review aims to provide knowledge for health care,nutrients supply,development of food and in vitro digestive models for children,thereby proposing future directions in related fields.
