Enostaven model absorbcije tekočine v prebavnem traktu

V članku je predstavljen preprost matematični model absorpcije vode v prebavnem traktu. Na začetku razvijemo modele za prenos hranil čez membrane, pri čemer se osredotočimo na pasivni transport skozi difuzijo in aktivni transport prek mehanizma Na+/K+ ATPaze. Na teh modelih zgradimo podrobnejši opis absorpcije vode. Analiziramo, kako različne količine Na+ vplivajo na absorpcijo vode ter preučujemo prilagoditvene odzive telesa na dehidracijo.

A simple model of fluid absorption in the gastrointestinal system

In this article, we present a simple mathematical model for water absorption in the gastrointestinal tract. We begin by developing models for nutrient transport across membranes, focusing on passive transport through diffusion and active transport via the Na+/K+ ATPase mechanism. Building on these models, we then define water absorption in greater detail. We analyse how variations in Na+ levels affect water absorption and examine the body’s adaptive responses to dehydration.
