Abstract:Objective: to study the dynamics of the human esophagus behavior when affected by Chagas disease. Methods: a mass-spring-damper model was proposed to model the food through the esophagus during peristaltic action. After that, parameters were recalculated to simulate a chagasic megaesophagus. Results: the velocity and displacement curves from both models were analyzed and the dynamic differences between the healthy organ and the ill one, identified. According to the results obtained, the food displacement in a … Show more
