WebStructure and Function of Small Intestinal Crypts The intestinal epithelium is the most vigorously self-renewing tissue of adult mammals [1]. It is specified from endoderm formed during gastrulation and remains as a stratified cuboidal epithelium until mid-gestation in most vertebrates [2]. WebLarge quantities of water are secreted into the lumen of the small intestine during the digestive process. Almost all of this water is also reabsorbed in the small intestine. Regardless of whether it is being secreted or absorbed, water flows across the mucosa in response to osmotic gradients. In the case of secretion, two distinct processes ...
