•A digestive transport model with multiphase content and compliant walls is proposed.•Vortical flow drives radial transport, nutrient absorption, and mixing of content.•Non-uniform solids distribution along the gut lead to changes in content rheology.•Presence of solids in digesta reduces intestinal...
