Compartmental Models in the Analysis of Intestinal Absorption

  • Giorgio Segre
Conference paper

Abstract

The kinetics of intestinal absorption can receive a simple mathematical formulation through the application of compartmental models. If one assumes the linearity of the system under analysis and calls X (t) the function which represents the fractional concentration in blood of a given substance at time t and X + (t) the function which represents the fractional concentration at time t of the same substance when given by mouth, (then between the two functions it is possible to write the equation
$$ {X^{ + }}\left( t \right) = \int\limits_{0}^{t} {G\left( \tau \right)X\left( {t - \tau } \right)} d\tau $$
