Small intestinal digesta comprises a viscous (Dikeman et al. 2007a) and shear thinning, i.e. pseudoplastic (Lentle and Janssen 2008; Lentle et al. 2002) particulate suspension that may behave as a weak gel (Bornhorst et al. 2013; Lentle et al. 2005). As discussed hitherto, the tendency to form ... Webflow of the gastric chyme into the duodenum occurs mainly when the peristaltic wave spreads over the middle of the antrum. In this phase the pylorus is relaxed (Fig. 2). Two factors are important for the flow of digesta into the duo denum: 1. the depth of the antral constriction, and 2. the degree of the pyloric relaxation. html element lang attribute
