Hydrodynamics in a villi-patterned channel due to pendular-wave activity
Rohan Vernekar, Faisal Ahmad, Martin Garic +4
Inspired by small intestine motility, we investigate the flow induced by a propagating pendular-wave along the walls of a channel lined with rigid, villi-like microstructures. The…

Intestinal villi and crypts density maximizing nutrient absorption
Martin Garic, Rohan Vernekar, Dácil I. Yánez MartÃn +3
The villi and crypts of the gastrointestinal tract increase the effective surface area of the intestinal mucosa, potentially enhancing nutrient absorption. It is commonly assumed t…
