Abstract
A theoretical study is presented to understand the effect of the longi tudinal electrical depolarization of the smooth muscle cells on the me chanics of the intestine. Our results show that: (i) the circumferenti al fibres are the main cause of the non-cylindrical deformed shape of the intestine, (ii) the mechanics of the intestinal contraction is ver y sensitive to the Young's modulus of the active fibre and to the musc ular tone, and (iii) the tissue pressure and the amplitude of the fibr e strain are maximal near the lumen of the intestine.
