WebNormal peristalsis was defined as esophageal contraction exhibiting amplitudes >30 mmHg at recording sites positioned 3 and 8 cm above LES. 12 The upper esophageal sphincter (UES) was also studied qualitatively, and the coordination between pharyngeal contractions and cricopharyngeal UES relaxation was assessed. WebDuring the peristalsis, the contraction of the ureter helps to move the urine in bolus form. In the current work, the ureter is modeled and a single peristalsis wave is used to know the effect of pressure and velocity at a different location in the ureter at different intervals of time for four inlet boundary conditions.
