The esophagus is a multi-layered organ that transports food to the stomach. While extensive biomechanical data exist for animal esophagi, human data remain limited. To address this, we analyzed residual deformations and zero-stress configurations in esophageal tissue from twenty-one cadavers (aged 2...
