The biophysical foundations and mechanisms of substance absorption in the gastrointestinal tract are analyzed in detail. The process of absorption through the cell membrane, its selective permeability, and its dependence on the concentration gradient are described. Types of passive transport—simple diffusion, facilitated diffusion, and osmosis—are explained, as well as processes that occur with energy expenditure. In addition, the processes of endocytosis and exocytosis, which play an important role in the entry and exit of large molecules into and out of the cell, are also clarified.
Keywords
