Lumen radius and layer thickness of esophagus

	Lumen Radius	Thickness of Mucosal Layers	Thickness of CM Layer	Thickness of LM Layer
Experimental data (mm)	3.5	1.85	0.55	0.49
Data used in the model (mm)	0.3	3.8	0.6	0.6

In the model, it was assumed the lumen in the resting state only contained a thin liquid film with radius as 0.3 mm. Geometric data used in the model were obtained based on experimental data and conservation of cross-sectional area (CSA). Experimental data are from Ref. 24. CM, circular muscle; LM, longitudinal muscle.
