[The diffusion of ethanol from blood into intestine: rates of transport (author's transl)].

Measurements of the ethanol flow from the blood into the gastrointestinal tract revealed an exponential characteristic. The rates of transport were proportional to the differences in concentration. The constants of the exsorption were equal to those of the insorption. The constants of the exsorption were 0.033 min-1 for the stomach, 0.071 min-1 for the small, and 0.019 min-1 for the large intestine.
