Intestinal absorption. I - General principles of transintestinal transport.
The paper deals mainly with the principles and the basic mechanisms underlying the transport processes of molecules across biological membranes. The simple diffusion of electrolytes and non-electrolytes, the chemically-facilitated diffusion and the active transport are briefly discussed. These transport mechanisms are utilized also by substances moving through the intestinal epithelium even if this tissue has a rather complex structure.
